Introduction

With the Canadian Space Agency currently preparing an Announcement of Opportunity for anew Small Payloads Program, this is an opportune time for a Community Workshop on Sciencefrom Suborbital Vehicles. The aim of this Workshop is to bring together those in the Canadianscience community who have an interest in using balloons, aircraft, rockets, and other unmannedvehicles as platforms for scientific exploration, and to get them dreaming about new ideas.

Such platforms offer a number of advantages that are closely allied to the mission of theCanadian Space Agency. These include:• Scientific exploration, including atmospheric science, space science, astronomy, and

astrophysics• Technology development, including testing prototypes of satellite instruments• Validation of satellite missions, such as those making height-resolved atmospheric

measurements• Training of scientific and technical personnel, who will become the next generation of

scientists, including our next generation of Principal Investigators

Goals

The goals of this Workshop, in anticipation of a new Small Payloads Program, include:• Raising the profile of balloons, aircraft, and rockets as platforms for scientific investigations• Stimulating discussion of new approaches and new science questions that can be addressed

with such platforms• Determining the level of interest in these flight opportunities in Canada• Identifying the infrastructure needed to enable new missions• Providing a vision for a “program” with regular flight opportunities• Enhancing and creating new collaborations between Canadian universities, government

agencies, and industry

Expected Outcomes

• A ten-year vision• A game plan for the next year• A list of potential new missions• A description of the infrastructure that will be needed for each platform, to allow such

missions to be accomplished• Recommendations for what is needed to maintain continuity

Ideally, we would like to see these outcomes providing input to the anticipated Announcement ofOpportunity for the new Small Payloads Program. If the timing of that AO makes thisimpossible, then we hope that these outcomes would provide input to the subsequent SmallPayloads AO.

The Organizing Committee will be submitting a Workshop Report to the Canadian SpaceAgency within two months of the meeting, and also plans to release this report to the community.

Background

Balloon platforms offer excellent opportunities for scientific exploration, particularly foratmospheric observations that look through the atmosphere, and for astrophysical observationsfrom above the atmosphere. They can carry a variety of payloads, including sampling, in situ,and remote sounding instruments, ranging from a few kilograms to several tons. They can fly ataltitudes from near the surface to the upper stratosphere, reaching near-space conditions at floataltitudes of 40 km. The duration of balloon flights can range from a few hours to several weeks,and they can be designed for special flights to match scientific requirements, such as valve-controlled slow descent, long duration flights, and tethered flights.

The time-scales for balloon missions are relatively short, typically taking from one to five yearsfrom concept to flight. Such missions allow testing of new instruments that may have little or noflight heritage in the near-space environment, enabling the assessment of their suitability forsatellite missions. Balloon programs are much less expensive than satellite programs, and havemany applications, including atmospheric chemistry and dynamics, radiation, weather andclimate, and astronomy and astrophysics. Balloons provide observations of detailed atmosphericprocesses on much finer spatial and temporal scales than is possible from the ground or satellites.

There have been recent technical advances in a number of ballooning technologies, for example,in trajectory control, super-pressure balloons, UV-resistant balloon materials, power systems,launch techniques, onboard storage, and telemetry, offering opportunities for Canadian industryto develop new strengths and capacities. These advances continue to improve the capabilities andreliability of scientific ballooning, making novel scientific investigations possible. These couldinclude such future Canadian missions as climate change and radiation balance experiments,long-duration Lagrangian (free floater) balloons for in situ chemistry measurements, andstratospheric wind measurements.

Canada has a long history of scientific ballooning, dating back to airglow measurements made in1960. Early efforts were led by the Canadian Armament Research and DevelopmentEstablishment, the University of Saskatchewan, and the National Research Council. In the 1970sand 1980s, the Atmospheric Environment Service led the Stratoprobe series of balloon flights,which led to the more recent MANTRA campaigns. Meanwhile, Canada has also been an activeparticipant in a number of high-profile international astronomy balloon missions, such asBOOMERANG and BLAST. We are now at a critical juncture with regard to future ballooningactivities in Canada. Environment Canada is reconsidering its support of the launch facility atVanscoy, Saskatchewan, and much of the existing payload and launch support equipment theredates back 20-30 years. Does Canada wish to maintain its own payload support and launchcapability or rely solely on contracting launches to organizations such as the Columbia ScientificBalloon Facility (CSBF; formerly the National Scientific Balloon Facility) in the USA or theCentre National d’Etudes Spatiales (CNES) in France? Without access to regular flightopportunities, it is difficult to build and maintain these capabilities. There are also questionsabout the trade-off between flight risk and resources; as currently implemented, ballooning is notsupported and managed as a space program in Canada. Moving to a risk avoidance model whereall systems are fully flight-tested will require an increase in resources, and is likely to movesome development out of universities and reduce student involvement.

Aircraft platforms offer high-altitude and long-range capabilities (up to 20 km and 11,000 km,respectively, depending on the aircraft) and provide high-resolution and high-sensitivitymeasurements using both in situ and remote sensing instruments. High-resolution measurementsare necessary for the study of the complex and small-scale dynamical, chemical, and radiativeprocesses in the lower troposphere (LT) and the upper troposphere/lower stratosphere (UTLS).Both the LT and the UTLS are regions of major interest concerning both climate impact andsurface environment. Changes in ozone, water vapour, and cloud properties and coverage in theUTLS have a large impact on surface UV fluxes and temperatures due to the radiative propertiesand particular temperature structure of this region. Significant ozone trends have been observedglobally and further changes in both ozone and water vapour are likely to occur in the future dueto a changing climate.

Aircraft measurements and the development of high-sensitivity and high-resolutioninstrumentation able to cope with low pressures and temperatures has the potential to improvepresent knowledge of the processes governing the chemical composition and the dynamicalstructure of the LT and the UTLS, and to monitor future changes. In order to study the UTLS,aircraft campaigns have to be designed to reach altitudes up to 16 or 17 km. On the instrumentalside, capabilities should include high resolution and accuracy for in situ measurements of O3 andCO, different long-lived tracers such as N2O, CH4, or SF6, halogen compounds, water vapour,and total water. A promising and highly valuable technique is offered by lightweight lidars forthe vertical profiling of aerosol, ozone, water vapour and wind. Both Canada’s industrial andscientific communities have considerable lidar expertise, offering opportunities for futuretechnological innovation and development, thus providing the prerequisite for scientific progress.

Instrumentation for the measurement of radiation and cloud microphysics is also needed.Although new cloud physics instrumentation has become available over recent years, muchcharacterization is still required to understand the accuracy of the measurements, and theinfluence of the aircraft itself and the physical instrument configuration on the measurementaccuracy. Progress in addressing several fundamental issues in cloud physics is still limited byinadequate or poorly understood measurements. Such measurements are required to improveunderstanding of cloud processes for a variety of applications, such as better cloud treatment inclimate change models. Cloud microphysical properties have been shown to strongly affectradiative fluxes.

Aircraft measurements thus present a valuable and indispensable tool to support the developmentand validation of multi-scale models and of satellite instrumentation. Historically, Canadianinstruments have often flown as payloads on American and European aircraft campaigns. InCanada, aircraft measurements have been supported by Environment Canada (EC) and theNational Research Council of Canada (NRC). EC and NRC have partnered in approximately 40cloud physics, air quality and climate studies over the past 13 years with the NRC Convair-580and Twin Otter aircraft, both of which have been conducted in the LT due to aircraft ceilinglimitations. The NRC Convair-580 aircraft (<7 km) has been developed by EC and NRC as aworld-class cloud measurement aircraft, and the NRC Twin Otter (<6 km) has been recognizedas a world-leading flux measurement aircraft. EC has also developed the NRC Twin Otter as amicrowave remote sensing platform as part of its cryospheric studies program. EC also owns andoperates its own Convair-580 aircraft, which has been developed mainly for synthetic aperture

radar surface remote sensing applications in conjunction with Natural Resources Canada(NRCan). Currently, EC and NRC are performing an airborne validation program for CloudSaton the NRC Convair-580 aircraft. The Twin Otter is active in a series of validation programs forAdvanced Microwave Scanning Radiometer (AMSR). NRC has recently been developing a T-33aircraft for higher altitude atmospheric measurements (up to a maximum of about 12 km), andalso possesses a Falcon-20 aircraft with larger cabin space capable of similar altitudes. However,it must be noted that as yet Canada does not have a well-developed high altitude airbornemeasurement platform.

Sounding rockets have been essential for developing new instrument concepts and training newinstrument PIs in Canada. Going from a high of as many as 70 launches per year from Churchillin the mid-1970’s, Canadian-led sounding rockets have all but disappeared, the last beinglaunched in 2000. For the time being, Canadian scientists continue to receive invitations toprovide instruments for rockets flown by other countries, the US and Japan being recentexamples. However, it is unclear how long this activity will continue to survive in this “hitch-hiking” mode.

Sounding rockets are used to probe altitudes spanning from the mesosphere to the upperthermosphere/ionosphere, with four-stage Black Brant XII’s reaching as high as 1500 km. The80-200 km range is effectively inaccessible by any other means. Above 200 km, soundingrockets offer many advantages over satellites: lower cost, short development time, freedom totest newer and riskier ideas, fewer constraints (typically) on mass, power, and telemetry, andability to choose the precise time and location of the trajectory. The major disadvantage, ofcourse, is that flights last less than 30 minutes, including the ascent and descent.

For decades, Canada has had the distinction of being the world’s foremost producer of civilianmotors: the Black Brant and Nihka. Bristol Aerospace also maintained a highly skilled andexperienced team of sounding rocket payload specialists. However as time goes by, access toboth resources – motors and expertise – becomes more and more uncertain.

Five years ago, Bristol announced that it could sustain a viable sounding rocket support programfor something like $1M per launch, provided a launch frequency of two per year could beguaranteed. However, a survey sent to CSA scientific advisory committee members at that timeshowed insufficient interest, and the idea was dropped. One-off type rocket projects would likelynow cost from $1.5-4M, not including scientific instruments. Still, one could argue that this costis more than offset by the significant reduction in risk for satellite instruments that wouldotherwise have no flight heritage.

What is Atmospheric Temperature?

*Adrian Tuck, NOAA-ESRL/CSD6Susan Hovde, CIRES, University of ColoradoShaun Lovejoy, Physics, McGill University

Abstract:

Time series of temperature, winds and ozone taken from ‘horizontal’ NASA ER-2 and WB57Faircraft flight segments are analyzed as statistical multifractals. A correlation between theintermittency of T and the observed photodissociation rate of ozone suggests that molecularspeed distributions may be non-Maxwellian, aided by a result from the molecular dynamicsliterature. Generalized scale invariance is observed for all variables with adequate noisecharacteristics, from 40 m to 7000 km. A similar analysis was performed for GPS sondesdropped from the NOAA Gulfstream 4 aircraft over the eastern Pacific Ocean during WinterStorms 2004. The results show that neither Kolmogorov -5/3 isotropic turbulence or Bolgiano-Obhukov -11/5 vertical scaling are obeyed. Instead, the exponent H = 2ß + 1 shows correlationwith vertical measures of jet stream strength, as it did with similar measures in horizontal flight.Homogeneous stable layers appear not to exist, there being instead a 'Russian doll' structure ofalternating, embedded stable and unstable layers arranged in a fractal way. Desiderata for futureinstrumentation of unpiloted aircraft are considered.

J. Walter Strapp*, D. Marcotte, S. Cober, G. Isaac, A. Korolev, M. Wolde, and R.Srinivasan

Abstract:

Environment Canada and the National Research Council of Canada have collaborated onairborne atmospheric research since the 1960s. The series of over 100 projects that has beenaccomplished reflects the topical areas of government atmospheric research over this time.Through the 1970s an 1980s, projects were performed mainly with the NRC Twin Otter researchaircraft in the areas of weather modification, cloud physics, and air quality. In 1993, the twoagencies formalized the relationship, committing up to 6 months of Twin Otter and 6 months ofConvair-580 aircraft time to environmental research. Since then, 40 environmental researchprojects have been performed in the fields of meteorological, air quality, and climate research.An overview of the program will be provided, along with a brief description of the researchaircraft and the instrumentation development.

Airborne atmospheric research at York University

Jim WhitewayDepartment of Earth and Space Science & EngineeringYork University

Abstract:

Recent airborne measurement campaigns have focused on the tropical tropopause region. Thishas included studies of gravity wave breaking, cirrus clouds, and the anvil outflow from tropicalconvection. These experiments have involved two aircraft. The Egrett was flown at heights of upto 15 km for in situ sampling, while a second aircraft (King Air or Twin Otter) was flowndirectly below the Egrett for laser remote sensing (lidar) measurements. Scientists on board thelow flying aircraft were able to view the lidar measurements in real time and decide on flightpatterns for the Egrett.

In the summer of 2007 there will be two airborne measurement campaigns. These will involvelidar measurements from a Twin Otter aircraft. For the first campaign in Southern Ontario theTwin Otter will carry a downward viewing ozone lidar for pollution transport studies. For thesecond campaign the Twin Otter will carry two upward looking lidars; one for measuring cloudsand aerosol, the other for ozone. The focus will be on the upper level outflow from pyro-convection around boreal forest fires. The goal is to determine if forest fire smoke is injecteddirectly into the stratosphere.

Utilization of suborbital measurements of tropospheric composition in the validation ofchemical data assimilation studies

Mark Parrington* and Dylan JonesUniversity of Toronto

Abstract:

We are studying the chemical and physical processes governing the distribution of troposphericozone and carbon monoxide through the assimilation of ozone and CO observations, from theTropospheric Emission Spectrometer (TES) on the NASA EOS Aura satellite, into two globalmodels of tropospheric chemistry and transport. Observations of tropospheric composition fromsuborbital vehicles (including instrumentation on both balloons and aircraft) are crucial tounderstanding the output from a chemical data assimilation system as they provide independent,high precision data on both assimilated and non-assimilated tracers in the system. Presented hereare results for March 2006 over North America, during which time the INTEX-B field campaignprovides a large number of aircraft and ozonesonde data.

Future of NASA Scientific Ballooning in Space and Earth Science Research

*David PierceNASA Balloon Program Office, NASA Goddard Space Flight CenterWallops Flight Facility, Wallops Island, VirginiaDanny RJ BallNASA Columbia Scientific Balloon Facility

Abstract

The U.S. National Aeronautics and Space Administration (NASA) Balloon Program continues tosupport the scientific community providing enhanced capabilities across a spectrum of balloonrelated space and Earth science disciplines. Long Duration Ballooning (LDB) continues to be aprominent element of the program with a mission model of a three-flight campaign fromAntarctica and the Arctic per year.

Long Duration Ballooning has set new expectations in the science community toward longerduration flights. NASA also completed development and flights of advanced ballooncraftsystems including the Command Data Module (CDM) as part of LDB missions launched fromAntarctica.

The Swedish Space Corporation/Esrange and the National Aeronautics and Space Administration(NASA) inaugurated a joint European / U.S. capability for LDB balloon flights from Sweden toCanada in June 2005 and will continue annually. This will complement the NASA / U.S.National Science Foundation Office of Polar Programs achievement of more than a decade ofsuccessful long-duration flights around Antarctica.

The Ultra-Long Duration Balloon (ULDB) project continues the development of a superpressureballoon capability for 60-100 day flights. An overview of the various aspects of the NASABalloon Program will be presented as well as the outlook for the future.

The contribution of long-duration balloon flights in the study of stratospheric dynamics:the example of Strateole/Vorcore

A. Hertzog(*)(1), F. Vial(1), Ph. Cocquerez(2)(1) Laboratoire de meteorologie dynamique, Palaiseau, France(2) Centre National d'Etudes Spatiales, Toulouse, France

Abstract:

In 2005, 27 superpressure balloons were launched from McMurdo (Antarctica) in the frameworkof the Strateole/Vorcore campaign. These balloons can fly for several months in the lowerstratosphere (17-20 km) where they behave as quasi-Lagrangian tracers of air motions. DuringVorcore, the scientific payload performed continuous observations of pressure, temperature andwind and the collected dataset is used to document the dynamics of the polar lower stratosphere.In particular, it will be shown that these data can provide unique information on the gravity-waveactivity in the lower stratosphere. Future superpressure balloon campaigns and new instrumentaldevelopments will also be presented, as well as the expected outcome of those new projects.

Probing the Atmosphere from Balloon Platforms

Kimberly StrongDepartment of PhysicsUniversity of Toronto

Abstract:

High-altitude balloon-borne platforms offer a number of advantages for atmosphericmeasurements. They can be used to carry payloads ranging from a few kg to several tons,consisting of extractive, in situ, and remote sounding instruments. These typically reach floataltitudes of 35 to 40 km, allowing the atmosphere to be probed from above rather than lookingup through the dense lower atmosphere, as must be done with ground-based measurements.Height-resolved measurements of atmospheric properties can be made on ascent, or from floatusing spectroscopic remote sounding techniques that scan through a range of elevations in solaroccultation or limb-viewing mode. Customized balloon flights, such as valve-controlled slowdescent, double ascent, or long duration “boomerang” flights, can be designed to match thescientific requirements. These enable instruments to make measurements over periods rangingfrom several hours to several weeks.

This presentation will summarize some of the capabilities, advantages, and disadvantages ofusing balloon-borne platforms to probe the atmosphere. Their usefulness for technologydevelopment and training of personnel will also be highlighted. The MANTRA (MiddleAtmosphere Nitrogen TRend Assessment) series of high-altitude balloon flights that have beenundertaken since 1998 will be used to illustrate some of these points. Future directions forballooning, and some thoughts on moving towards a new Small Payloads Program in Canadawill also be discussed.

Balloon-borne Infrared Spectrometer Systems Operated by the University of Denver

*Pierre Fogal, Department of Physics, University of TorontoRonald Blatherwick, Frank Murcray, Department of Physics, University of Denver

Abstract:

This presentation provides a brief recap of some of the technology and results of the ballooningprogram carried out by the Murcray Group at the University of Denver over the past threedecades. During that time, primarily infrared measurements of the atmosphere were undertakenusing two types of spectrometer, namely the now ubiquitous Fourier Transform Spectrometer(FTS) and cooled grating spectrometers. These instruments were deployed in various missionscenarios, ranging from a single instrument high resolution FTS, to multiple instrument gondolassuch as the Middle Atmosphere Nitrogen Trend Assessment (MANTRA) and the ImprovedLimb Atmospheric Spectrometer (ILAS) flights, to small sonde-like balloons. Two FTS, bothconstructed by Bomem of Canada, one having an apodized resolution of approximately 0.002cm-1 and the other of approximately 0.02 cm-1 were operated in solar transmission mode torecord solar occultations at sunrise and sunset. The cooled grating instrument was designed inhouse, and is known as the Cryogenic Atmospheric Emission Spectral (CAESR) radiometer.CAESR was usually configured to record atmospheric emission data on ascent.

PIOS: a miniature optical sensor for measuring atmospheric trace gases

Mareile Wolff*, University of TorontoAndreas Herber, Alfred Wegener Institute for Polar and Marine Research, GermanyWilfried Ruhe, impres GmbHOtto Schrems, Alfred Wegener Institute for Polar and Marine Research, Germany

Abstract:

The Platform Independent Optical Sensor (PIOS) was developed for simultaneous measurementsof trace gas profiles in the atmosphere. Its measuring principle is based on the detection of solarirradiance with a miniature spectrometer (Ocean Optics, Inc., FWHM = 1.3 nm). The widespectral coverage of the miniature spectrometer (200-850 nm) offers the possibility formeasurements of trace gases which absorb within this wavelength range, e.g. O3, NO2 and BrO.

In the first application, PIOS was combined with a commercial radiosonde to produce a balloon-borne version. The sensor can be operated anywhere in the world due to its low weight (1.7 kg)and the autonomous portable telemetry system. Nine balloon-borne PIOS sondes has beenlaunched during two field campaigns: 2004 in Ny-Ålesund, Spitsbergen and 2005 inHohenpeißenberg, Germany.

The irradiance measurements depend strongly on the instrument's temperature. The temperature-induced wavelength shift, the absolute irradiance, and the dark signal behaviour werecharacterized depending on the change of the spectrometer's temperature. Based on the pre-flightlaboratory characterization, an inflight correction for changes in the dark signal and for thewavelength drift was applied.

In a first demonstration of the new sonde's performance, ozone profiles were retrieved from theflight measurements with an adapted Dobson spectrometer algorithm. The ozone profilesobtained were compared with ozone profiles measured simultaneously by ElectrochemicalConcentration Cell (ECC) ozone-sondes and a lidar system. The PIOS results agree with thecomparison profiles within 20% for altitudes between 15 km and the burst point of the balloon.In the lower stratosphere and upper troposphere the discrepancies increase.

PIOS was planned and constructed for operation on board other suborbital platforms. A rocket-borne version exists and successfully passed all pre-launch tests for launch on board a researchrocket. An implementation on board a remote controlled UAV (unmanned air vehicle) is possibleand would allow several missions with the same PIOS instrument along controlled flight paths.

Overview of the NASA Sounding Rocket Program - Unique Scientific and TechnicalCapabilities and Achievements

Robert F. Pfaff, Jr.NASA/Goddard Space Flight Center

Abstract:

For over four decades, NASA’s Sounding Rocket Program has been a jewel in the crown of theagency’s spaceflight capabilities. The program rests solidly on 3 critical elements: (1) Unique,cutting edge science missions, (2) Platforms in space for the conception, testing, anddevelopment of new technology, and (3) Training ground for students, young researchers andengineers. Two additional important features of the program are its low cost and its rapid, quickresponse.

Sounding rockets carry scientific instruments into space along parabolic trajectories, providingnearly vertical traversals along their upleg and downleg, while appearing to "hover" near theirapogee location. Whereas the overall time in space is brief (typically 5-20 minutes), for a well-placed scientific experiment launched into a geophysical phenomena of interest, the short timeand low vehicle speeds are more than adequate (in some cases they are ideal) to carry out asuccessful scientific experiment. Furthermore, there are some important regions of space that aretoo low to be sampled by satellites (i.e., the lower ionosphere/thermosphere and mesospherebelow 120 km) and thus sounding rockets provide the only platforms that carry out direct in-situmeasurements in these regions. Astronomy, solar, and planetary science missions includesophisticated telescopes with optional joy-stick operated, sub-arc-second pointing ofastronomical objects, including those too close to the sun for Hubble Telescope observations.Microgravity missions are carried out on high altitude, free-fall parabolic trajectories, whichprovide ideal microgravity environments without the vibrations frequently encountered onhuman-tendered platforms. In this presentation, an overview of NASA’s Sounding RocketProgram will be provided with an emphasis on its technical and scientific capabilities and recentachievements.

Development of the Suprathermal Particle Imager and the Role of Sounding Rockets

David KnudsenDepartment of Physics and AstronomyUniversity of Calgary

Abstract:

The Suprathermal Particle Imager began as a concept study in 1996 and has since evolved into aflight-proven research tool for measuring ionospheric temperature and flow velocity. Soundingrockets were the key to proving the concept and demonstrating the scientific potential of the SPI.This talk reviews the development of the SPI, highlights its scientific accomplishments, and askswhether a similar development would still be possible in today's Canadian research environment.

The History of Canada’s Black Brant Suborbital Rocket

Andrea LegaryBristol Aerospace Limited

Abstract:

Canada’s early space science program made great use of the research benefits offered bysuborbital rockets. The benefits included the ability to take measurements at the altitude betweenthe minimum altitude of satellites and the maximum altitude of balloons. Suborbital rocketsprovided a relatively fast response capability, permitting scientists to conduct their experimentsat a time and pace of their choosing. Bristol's involvement in a typical suborbital rocket missionusually lasted approximately two years from project start to launch. Suborbital rocket programswere also considerably less expensive than satellite missions. While the rocket missions of thelate-1980s and 1990s were becoming more complex and expensive compared to the missions ofthe 1960s, they were still less costly than a normal satellite mission. The Black Brant supporteda wide variety of space science missions including, space physics, astronomy, and microgravityresearch, among others. Since its first launch in 1962, more than 1,000 Black Brant rockets werelaunched from 21 sites around the world. Although it has been years since the last Canadian-ledsounding rocket was launched, Bristol still possesses the knowledge and expertise required forthe support of these missions.

Development of a prototype Langmuir probe for the ICI-1 sounding rocket

Johnny AaseDepartment of Physics and AstronomyThe University of Calgary

Abstract:

In this talk I will describe the development of a prototype Langmuir probe for the ICI-1(Investigation of Cusp Irregularities) sounding rocket, which was my Master thesis work at theUniversity of Oslo, Norway.

This instrument was designed to obtain an electron density profile of the polar cusp ionosphereover Svalbard in the Norwegian Arctic at altitudes between 90 and 300 km, and resolve HFbackscatter targets in the F layer. The probe would measure large-, meso-, and microscalevariations in the electron density, and also provide data for determining the rockets spin rate andattitude. Near apogee the spatial resolution would have been half a meter.

The probe was a hollow 30 millimeter diameter aluminium sphere. It was mounted on adeployable instrument boom. The electron-collecting hemisphere was biased with a +3.3 Vvoltage. The sampling frequency was 2 kHz. The rocket was launched from Ny-Aalesund onSvalbard in November 2003, but was lost 17 seconds after launch.

I will also briefly discuss the Norwegian cost-effective Hotel Payload concept being developedby Andoya Rocket Range.

Case Study of a Hitch-hiker: The Thermal Suprathermal Analyzer (TSA) Instrument onthe Japanese SS520-2 Rocket

Andrew YauUniversity of CalgaryDepartment of Physics and Astronomy

Abstract:

The Thermal Suprathermal Analyzer (TSA) is a recent example of a Canadian instrument hitch-hiking on a foreign (Japanese) sounding rocket and subsequently evolving into a satelliteinstrument. The SS520-2 rocket was launched in December 2000 from Spitsbergen, for study ofion acceleration and outflow in the topside cleft ionosphere. The successful flight of TSA onSS520-2 has led to an opportunity to fly the Suprathermal Ion Imager instrument in an upcomingfollow-on flight in 2007. We discuss our experience and lessons learned in the SS520-2 project,the benefits, drawbacks, and challenges of "hitch-hiking mode" sounding rocket experiments,and our vision of life in the hitch-hiker lane. In addition, we explore possible strategies tooptimize or create future "hitch-hiking" and other flight opportunities.

A New Approach for Observing Ice Crystal Habit in Model Cirrus Clouds

M.E. Earle*: Department of Chemistry, University of WaterlooT. Kuhn: Department of Chemistry, University of WaterlooI.A. Grishin: Department of Chemistry, University of WaterlooJ.J. Sloan: Department of Chemistry, University of Waterloo

Abstract:

Physical and chemical information about cloud particles is of great importance to theunderstanding and prediction of climate change because the sizes and morphologies of cloudparticles greatly influence light scattering and consequently the redistribution of solar energy inthe atmosphere. In particular, ice crystals in cirrus clouds exhibit a variety of sizes, shapes andhabits, depending on the ambient temperature and relative humidity during their nucleation andgrowth phases. The ability to predict the properties of the cloud particles and hence their effectson atmospheric radiative transfer is essential for climate modeling.

To this end, we have developed a means of imaging micron-sized ice particles in the laboratoryunder temperature conditions representative of those in cirrus clouds. The conditions are createdwithin a cryogenic aerosol flow tube developed over the course of the past decade, comprising atemperature-programmable flow section capable of cooling to 150 K. Ice crystals formed fromaqueous aerosols over a range of experimental temperature and flow conditions are then imagedusing an optical microscope coupled to a CCD camera. The resulting images are of extremelyhigh resolution (~ 1 um), allowing the structural details of the various ice crystal habits to beexamined. Furthermore, the imaging results can be compared with the results from infraredspectra of ice particles obtained under the same conditions.

Here we will present our methodology within the framework of its feasibility for use in airborneaerosol measurements, and show examples of ice crystal habits obtained from micron-sizedaqueous aerosols between 240 and 213 K. We will also discuss how imaging data have beenused to validate our method of FTIR retrievals. In a companion presentation, we will discuss theimage processing algorithms we have developed to determine the size and shape informationfrom the images and present the results obtained from these algorithms.

Image Processing Method for Retrieving Ice Crystal Habits in Cirrus Clouds

I.A. Grishin*, M.E. Earle, T. Kuhn and J.J. SloanDepartment of Chemistry, University of Waterloo

Abstract:

Light scattering by ice particles in cirrus clouds depends on particle size, shape and habit, asdetermined by prevailing temperature and humidity conditions. The characterization of icecrystal habit in cirrus clouds is therefore an important step in establishing their effect on theEarth’s radiative balance.

We have built an optical microscope assembly to record images of model cirrus cloud icecrystals created in a cryogenic flow tube under carefully controlled laboratory conditions. Thedetails of this apparatus will be presented in a companion presentation. We have also developedimage processing techniques capable of extracting size and shape distributions of the particles.These algorithms are based on the localization of contrast regions in the original image, followedby morphological analysis of the particle edges. Using this approach in combination with themethod of moments, we can retrieve information about the particle size, aspect ratio (asphericityparameter) and compactness and relate this to the particle formation conditions.

The method was applied to the retrieval of size and shape distributions of water, sodium chlorideand ammonium sulfate aerosols in the temperature range 213 - 243 K. Here we will illustrate theutility of these algorithms in characterizing ice particles in model cirrus clouds, and discuss theadvantages and limitations of this approach.

The dream of a Canadian high-altitude research aircraft ...

Michaela I. HegglinUniversity of Toronto

Abstract:

Why should the Canadian science community be interested in a high-altitude aircraft? What arethe scientific questions related to the region between 8 and 16 km altitude commonly referred toas the upper troposphere/lower stratosphere (UTLS) region? What benefits would aircraftcampaigns yield for the satellite community? These questions will be addressed during thispresentation by using examples of past aircraft campaigns aimed at the study of tracerdistributions in the UTLS region. It will further include a perspective on the use of aircraftmeasurements for satellite validation by showing comparisons between the SPURT aircraft dataset and ACE satellite measurements.

NRC High Altitude Atmospheric Research Aircraft

Anthony P Brown*, John Aitken, Dave Marcotte, Camile Lebrun, Mike Pygas, MatthewBastian and Roy Vestrum

Abstract:

The CT-133 of the Flight Research Laboratory of the NRC has recently been re-instrumentedwith high fidelity and ultra-fast response inertial and air data instrumentation systems, to providea high altitude research capability for harsh atmospheric environments, such as turbulence(including wake vortices), jet aircraft engine exhaust (for emissions measurements) and ice cloudenvironments. The ruggedness, accuracy and reliability of the FRL Inertial Reference andNavigation System (FIRNS) has been demonstrated in FRL research aeroplanes at extreme Eulerangles and very high rotation rates of 300 deg/sec. A unique air data system has been designedand fitted to the CT-133. It features sensors optimized for ultrafast response to changes in airdirection, such as that occurring during flight in turbulence. Air and inertial data are measuredand recorded at 600 Hz, which at high-altitude sampling airspeed, is equivalent to Nyquistsampling lengths of 0.5-0.6 metres along-track and, depending upon cross-track velocity, 1-2 cmacross-track. Vectorial differencing enables the derivation of the 3D wind vector, also at 600 Hz.The systems installations were completed in spring 2006. Following airworthiness flight tests,air data developmental testing and calibration flights were conducted in May 2006. An initialwake turbulence measurement and verification flight was conducted on 26th May 2006, duringwhich wake vortex flowfields of A310, A318 and B767-300 aircraft were surveyed in a stratifiedatmosphere amidst widespread thin cirrus. Vortex core traverses were conducted. The 600 Hzsampling provided flowfield insight not previously available in earlier NRC wake vortexflowfield surveying, in particular vortex core characteristics such as axial-flows and “super”-tangential velocities within the core. Initial data analysis and reporting has been conducted.

Underwing pods, for the carriage of microphysical and air chemistry instruments, have beendesigned and are presently being fabricated. The initial application shall be the airborne andrunway measurement of aircraft emissions, under collaborative research agreements withTransport Canada (TC) and Environment Canada. For this purpose, the pods will carry airchemistry instruments, including an Lii200 black carbon sensor, Thermo NOx analyzer, CNaerosol counter and a flask air-gathering system. The emissions data shall be used in thedeliberations of TC with ICAO and the international community on emissions standards. TheFRL also has collaborated upon an IPY proposal to use the CT-133 for pyro-Cb emissionsmeasurements in the upper-troposphere and tropopause, as one of a multi-aircraft experiment onthe transport and transformation of Boreal forest fire emissions.

The capability of the NRC Falcon 20 complements that of the CT-133. The Falcon is a transportaircraft, and therefore is not as suitable for in-situ harsh environemnt measurements. However, itis a cabin-class aircraft, and as such is a suitable platform for near-field remote sensing, such asusing LIDAR sensors. The aircraft is readily suitable for such modifications, in particular opticalglass inserts could replace cabin windws, and mrror arrangements enable the LIDAR beams tobe projected upwards and downwards, as requirements dictate.

*Jim Whiteway and Brian SolheimDepartment of Earth and Space Science & EngineeringYork University

Walter StrappEnvironment Canada

Abstract:

The airborne atmospheric research at York University mainly involves laser remote sensing(lidar) in combination with simultaneous in situ measurements. The focus of this research willcontinue to be placed on the tropopause region. This includes measurements of dynamics,composition, and cloud physics. The next step in this research program will be to achieveairborne lidar measurements of both water vapour and ozone in the tropopause region. Plans arecurrently being discussed for a proposal to install lidar systems in the Falcon aircraft operated bythe Flight Research Laboratory at the National Research Centre (NRC). The Falcon will also beapplied for testing instruments developed for remote sensing from earth orbit. This proposal willalso involve applying the NRC T-33 aircraft for in situ measurements at heights up to 13 km.

What is Validation Anyway?

James R. DrummondDepartment of Physics and Atmospheric ScienceDalhousie University

Abstract:

As satellites become more ubiquitous and more significant in our understanding and monitoringof earth systems, the reliability of satellite data becomes a matter of great importance.

The final step in the assessment of satellite data is validation and is especially significant forsatellites because of the single-sensor nature of the measurements; the inaccessibility of thesensor for any troubleshooting and adjustment that was not anticipated at the design stage; andthe often inherently complex methods of extracting the scientific data product from the rawmeasurements.

Since validation is often performed with sub-orbital instrumentation, this topic is of considerableinterest in the context of this workshop. This talk will explore what we mean by validation: howit is achieved; how it should be achieved; the gap between the two; and what can be done tobridge the gap.

"If I had $1M."

Matthew Toohey* and Debra Wunch*University of Toronto

Abstract:

As student "veterans" of the MANTRA balloon campaigns, we have a unique perspective on thestructure and effectiveness of the Canadian balloon program - especially as it relates to trainingand HQP development. We would propose to combine our respective millions to create a balloonprogram with two distinct parts, each satisfying a well-defined goal: one that consists of a set of"flagship" instruments, with the primary goal being scientific, and one that consists of smallpayloads that contain "development" instruments, with the primary goal being the training ofHQPs. The scientific success of the flagship stream (modelled after, say, MkIV, BLAST orSAOZ BrO payloads) would encourage a commitment to ballooning which would be veryvaluable to students working on the developmental stream, since guaranteed launches withsufficient funding and support personnel are critical to timely and successful student education.

Argus Suborbital Flights

*Dr. Brendan QuineDirector of Space Engineering, York University, and Technical Director, Thoth Technology.Rajinder JagpalGraduate Student, York University.

Abstract:

Argus is an advanced system to monitor greenhouse-gas emissions from space and represents anew generation of miniature remote sensing instrumentation. York University and ThothTechnology have worked together on the design and development of the 250 g Argus instrumentto monitor greenhouse gases in the surface-to-lower-troposphere region. Operating in theinfrared and in a nadir-viewing mode, Argus provides a capability for global pollutionmonitoring of specific targets at one-kilometer surface resolution. We will identify and measuresources and sinks of greenhouse gases, as well as find and track pollution plumes from large-scale, industrial activity. As part of the Can-X 2 microsatellite developed by UTIAS, the firstlaunch of an Argus instrument is scheduled for 2007 on India’s PSLV.

We seek flight opportunities on aircraft and balloon based platforms in order to validate andenhance this sensing capability. In one flight scenario, we propose validation flights of Argusinstruments onboard one or more hand launched, high altitude balloons. We assume that payloadstabilization and pointing control are not required and that missions do not require altitudecontrol, eliminating a requirement for a ballast system and descent valves. The balloon payloadwill be suspended from the balloon with a pendulation of typically less than two degrees andwith an expected revolution below one per minute. The Near Space environment is highlyanalogous to space environments with similar pressure and thermal regimes. Preflightqualification of integrated flight systems will be conducted at York University’s new Space-TestFacility.

Skycam Tethered Aerostat for the Inukshuk Landed Rover Canadian Mission to Mars

Roman. V. Kruzelecky*, Brian Wong, Emile Haddad, and Wes Jamroz,1 Ed Cloutis,2Nadeem Ghafoor3

1MPB Communications Inc., 151 Hymus Blvd., Pointe Claire, H9R 1E9, Quebec,[email protected];2 Univ of Winnipeg, Dept. of Geography, 515 Portage Ave., Winnipeg, MB, R3B 2E9,[email protected];.3MDA Space Missions, 9445 Airport Rd, Brampton, Ontario, Canada L6S 4J3,[email protected].

Abstract

The Inukshuk mission addresses key science themes of CSEW4; focusing on the search forhydrated mineralogy and subsurface water sites that can provide evidence of past or present lifeusing an innovative landed rover. Mission cost effectiveness is achieved through a synergisticinstrument suite based on advanced but mature patented MPBC miniaturization technologies thatenable high IR spectral measurement performance with minimal mass and power. Newexploration and science will be accomplished using an innovative tethered combination of asmall rover and a self-elevating Skycam aerostat with VIS imager.

The Mars Skycam elevating aerostat, at 5 to 10 m altitudes, will provide an informative high-resolution 2-D view of the rover below and surrounding terrain to greatly assist the semi-autonomous navigation of the rover around obstacles and the selection of sites for more intensivesubsurface investigations using the Inukshuk MDA robotic driller to depths of about 1 m.

Balloon designs proposed for planetary missions have involved a number of approaches. One isthe solar Montgolfiere hot-air balloon where the envelope is made from a material that traps heatfrom sunlight, or from heat radiated from a planetary surface. Another approach is a "reversiblefluid" balloon. This type of balloon consists of an envelope connected to a reservoir, with thereservoir containing a fluid that is easily vaporized. The balloon can be made to rise byvaporizing the fluid into gas, and can be made to sink by condensing the gas back into fluid.

The first planetary balloon mission was successfully performed by the Russian space agency incollaboration with the French space agency CNES in 1985 using spherical super pressureballoons. A small balloon, similar in appearance to a terrestrial weather balloon, was carried oneach of the two Soviet VEGA Venus probes, launched in 1984. The first balloon was insertedinto the atmosphere of Venus on June 11th, 1985, followed by the release of second balloon onJune 15th, 1985. Each of the balloons operated for about two Earth days until their battery powerwas consumed.

The Inukshuk skycam aerostat will employ a refillable superpressure structure about 1.5 to 2 min diameter with a He reservoir on the rover that can be used to periodically replenish theaerostat He fill. For buoyancy, the blimp must displace a volume of the Mars largely CO2atmosphere with a mass exceeding the combined weight of the blimp, interior He gas and the

tether. The available lift for a Mars blimp is about 12 g/m3 for a pressure near 7 mbar and airtemperature near 0oC. The operating Mars conditions are similar to those encounteredterrestrially at the higher 30 to 40 km altitudes. The skycam will employ a-Si solar cells onflexible CPI to provide about 1 Watt peak power for the onboard VIS imager(s) and otherminiature sensors with an RF data link to the rover.

Preliminary schematic of Skycam aerostat tethered to rover.

The added science that can be accomplished using the Sycam aerostat includes measuring thenear surface atmospheric conditions such as the temperature distribution between the rover andskycam using a serial string of miniature FBG temperature sensors along the tether. Near-surfacewind conditions can be monitored using an opto-isolated miniature rotor for wind speedmeasurements at the Skycam altitude.

Near surface atmospheric studies between the rover and aerostat will be accomplished using theMPBC tuneable fiber laser to provide very high spectral resolution measurements of CO2 andCH4 in the bands near 1600 nm, and their isotopic composition, with about 5-10 pm wavelengthresolution. The CH4 is of high interest from a planetary biology perspective.Near end of mission, it is hoped to release the Inukshuk Skycam to provide a sojourn acrossMars with data link to the rover or an overhead communications satellite.

Abstract:

With orbits and masses of hundreds, and radii of tens of planets around other stars known, thelogical next step is to obtain an actual image. This requires extremely high contrast, especially ifone wishes to detect the planet when it is least like a star, with its emission dominated byreflected light. Such high contrast is difficult if not impossible to achieve from the ground, sinceit would require correction for seeing due to atmospheric turbulence beyond current or near-future capabilities. Thus, space missions have been considered, using either a coronograph or anulling interferometers to remove or cancel most of the host star light. It should not be necessaryto go to space, however: from a stratospheric balloon, with only 1% of the atmospheric columnone has from the ground, seeing is not an issue any more. What might be a problem, isaccelerations due to changing winds, which cause pointing instabilities and mirror deformations.With periods longer than a second, these are relatively slow, however, and it should be possibleto correct for them using active optics.

Our proposal is to fly a prototype nulling interferometer on a balloon to test the feasibility ofobtaining very high contrast imaging, using a slightly updated instrument built for the PICTUREsounding rocket experiment, matched to a telescope with an aperture of 1.25 m. We prefer thenulling interferometer over a coronograph since it allows for high contrast closer to the host star,and thus requires a smaller telescope for a given star-planet separation.

The main goal of the mission would be to test the feasibility of observing from a balloon, anddetermine whether the next step should be space, or, whether in fact a mission with a largermirror (up to 3 meter) is possible. Such a mission would be especially interesting if the nextgeneration of ultra-long duration balloons becomes available (or, even better, stratosphericzeppelins).

While the main goal is to test feasibility, the observations might lead to interesting science ontheir own. Specifically, among the known extrasolar planets, the one around Epsilon Eridanishould be detectable, and other obvious targets would be the debris disks detected around a largenumber of stars.

If I had a million dollars: In search of cold ionospheric currents

Johnathan BurchillNatural Resources Canada, Geomagnetic Lab

Abstract:

A great success story in space physics was the prediction and confirmation of electric currents inthe auroral upper atmosphere. These currents play a key role in the electrodynamic couplingbetween the ionosphere and the magnetosphere. The role of sub-eV ionospheric electrons in thiselectrodynamic coupling remains poorly understood, however, and direct detection of theirspectra remains elusive. I will review the science behind these cold ionospheric currents, anddiscuss a sounding rocket mission to investigate them directly.

Suborbital instrument projects at ABB Bomem

Frederic Grandmont*, Marc-Andre Soucy, Jacques Giroux, Henry BuijsABB Bomem

Abstract:

ABB Bomem was founded in 1973 in the foot step of Dr. Henry Buijs thesis work on FourierTransform Spectroscopy measurement in the infrared (FTIR) from balloon. Even though thecompany growth came primarily from the commercial applications of FTIR, the company alwaysremained dedicated to support research projects and experiments that could benefit from FTIRtechnology. In the nineties, the company expanded its R&D based activities to include spaceapplications such that the ABB Bomem name is now known as a world leader in FTS spaceinstrumentation. Its most well known instruments are the SciSat payload launched in 2003primarily to measure tropospheric ozone. Another important achievement is NOAA's nextgeneration of polar-orbiting weather satellite which payload will include an FTS-based sounderbuilt by ABB Bomem and ITT Industries. Also of interest is Japan GOSAT mission which aimsat measuring Greehouse gas concentration to support the Kyoto protocol.

Such important space missions are always preceded by a series of demonstration and researchinstruments taken to sub-orbital elevation to help build a science case, validate or calibrate thesatellite data output. A list of airborne/balloon borne instruments projects conducted at ABB willbe presented.

High-altitude Balloon Flights as a Test and Operations Platform for Lidar Systems

John F. Hahn, Optech Incoporated

Abstract:

High-altitude balloon flights offer potential benefits to lidar instrument development andoperation. This paper is intended to promote discussion of these benefits and possibleapplications. High altitude balloon flights can deliver to the user a space-like environment,prolonged flight duration and payload retrievability, all of which are valuable in the test of lidarinstrumentation. Space lidar instruments, beyond the breadboard but not yet at the engineeringmodel stage of development, can be tested and demonstrated for extended periods of time. Thiswould constitute the advancement of the instrument’s technology readiness level (TRL) to TRL-6: System/subsystem model or prototype demonstration in a relevant environment (ground orspace). TRL-6 is considered the threshold level of preparedness acceptable for spaceflight.

More commonly, an engineering model is built and tested on the ground, includingthermal-vacuum tests that can last up to several days. While ground-based T-vac testing has theclear advantage of offering accessibility to monitoring instrumentation, prolonged operation oflidar systems in such circumstances may prove problematic. Operator eye-safety and safetywithin the laboratory must be considered. Demonstrating the capability to retrieve useful scienceinformation requires coupling the lidar to the outside world through multiple windows. And thelaser, as the most problematic element in the lidar system, is tested in the relevant environmentfor a period of time substantially less than typical mission lifetimes. Flying lidar instrumentationon a balloon, however, can offset these limitations. Once aloft, there are few operator safetyissues and no difficulties in coupling the instrument to the outside world for demonstration /intercomparison purposes. Since balloon payloads are retrievable and since ample data could becollected in this test case, instrument development could be accelerated, given the availability ofroom on balloon flights.

Operationally, the slow-drift / prolonged dwell potential of balloon flights makes itpossible for high density data to be collected over geographically remote regions. Thesecapabilities, it would seem, could do much to improve the quality of the topographical models inremote regions, in terms of both vertical accuracy and horizontal resolution. The density of dataprovides attendant advantages to the measurement statistics. Moreover, full waveform signalcollection from lidar systems flying over forested areas can be used to estimate the biomass ofthe area, an important step towards establishing the planetary carbon budget. The experimentaldata can further be used to develop more accurate vegetation scattering models, for instrumentmodeling or interpretation purposes. Balloon-borne data of this type would be a useful high-spatial resolution complement to orbital vegetation canopy mapping, providing tie points to datacollected from space, making for robust interpretation of all collected data.

PROSPECTS OF DEVELOPING BALLOON-BORNE GAS SENSORS BASED ON LONG-WAVELENGTH VCSELS FOR IN SITU CHEMICAL ANALYSIS OF THE ATMOSPHERE

Alexandre Lytkine*, Wolfgang Jaeger, and John TulipECE Dept., Chem. CentreUniversity of Alberta9107-116 Street, Edmonton, AB, Canada T6G 2V4

Abstract:

Long-wavelength vertical-cavity surface-emitting lasers (VCSELs) with a buried tunnel junctionwhich are currently commercially available from VERTILAS (Germany) possess a uniquecombination of properties valuable for the development of novel instrumentation for in situchemical analysis of the atmosphere using unmanned vehicles. Some of these properties are: 1)almost continuous coverage of the spectral range between 1.3 and 2.0 um with a narrow-linewidth laser emission; 2) continuous tuning of individual VCSELs over intervals up to 20 nm;3) the capability of producing single-mode emission with predictable parameters (such asfrequency, linewidth, power) in a wide range of operation parameters; 4) circular output beamfacilitating a compact fiber-optical architecture of gas sensors; 5) capability of being modulatedby injection current at frequencies up to few GHz allowing for the application of ultra-sensitivegas detection techniques; 6) ultra-low power consumption. We will present the results of ourstudies of the VCSELs operating near 1512 nm, 1577 nm, and 1564 nm and suitable for ultra-sensitive detection of NH3, CO2, CO, CH4, H2S, and H2O. To simulate a wide range ofmeasurement conditions we have developed an absorption cell allowing to control gastemperature and pressure in the ranges of 100 - 300 K and 10-3 - 1 bar, respectively. The designof the cryogenic absorption cell and the results of preliminary experiments on gas sensing withlong-wavelength VCSELs at low temperatures and low pressures will be presented.Measurement strategies and a concept design of compact VCSEL-based balloon-borne gassensors for in situ chemical analysis of the atmosphere will be discussed.

Abstract:

Validation of satellite measurements is an important and challenging exercise. In the case ofNO2 and BrO, this activity is particularly difficult given that both species have a significantdiurnal variability and that the independent measurements to be used for the validation activityare often not co-located in time with the satellite measurements. Models can be used to reconcilethe timing of the measurements, but the small number of available measurements remains amajor problem for many validation activities. Most frequently, information about the verticaldistribution of the species in question is required and although this information can be obtainedfrom balloon measurements, balloon flights are rather rare and normally do not span all thedesired seasons and locations. Ground-based measurements are more regular but although theymay contain information about the vertical distribution of the species in question, this is usuallyat low vertical resolution. Therefore, opportunities when co-located ground-based and balloonmeasurements are available become particularly useful for validation activities: the balloon-based profile can be used to assess the ground-based retrieval at the same time as the satelliteprofiles. In addition, the ground-based measurements may span many days, thereby enhancingthe likelihood of co-locations with the satellite observations. In this paper we presentcomparisons of NO2 and BrO vertical distributions measured from a balloon-borne SAOZinstrument, from ground-based zenith-sky spectrometers, and from two satellites: ACE andENVISAT. The balloon and ground-based measurements were taken from mid-latitude duringsummer as part of the MANTRA 2004 campaign.

Abstract:

MANTRA was directly linked to the storied history of Canadian balloon-based stratosphericobservation through the participation of two emission radiometer instruments. These specificinstruments were fabricated as part of a set of virtually identical models in the 1970's, and weredesigned to measure atmospheric thermal emission in the 715-1250 cm-1 range, from which thevertical mixing ratio profile of HNO3 could be retrieved. The emission radiometer was anintegral component of the Stratoprobe missions of the 1970's and 1980's, and a number ofindependent Arctic and midlatitude missions. The instruments were resurrected with the idea thatdata collected during MANTRA campaigns, as well as available data collected during flights ofthe 1980's and early 1990's could be analyzed consistently with an improved profile retrievaltechnique. Successful completion of this goal should result in a long-term data set of trace gasprofiles, spanning a time period of significant changes to the chemistry of the stratosphere. Sucha data set could prove valuable in testing current understanding of the chemical balancesinvolving ozone and nitrogen species, and how the relationships have changed with time. Wepresent a description of the improved retrieval technique developed and some retrieved profileresults. We also include discussion of the strengths and weaknesses of the emission radiometertechnique, and a discussion of issues related to the detection of long term trends with balloon-based observations.

Abstract:

The Middle Atmosphere Nitrogen TRend Assessment (MANTRA) high-altitude ballooncampaigns have provided a forum for dynamical research and instrument development.Campaigns were held in Vanscoy, SK, at a scientifically and practically advantageous time ofyear called turnaround, when stratospheric zonal winds change from easterly to westerly. Aclimatology of zonal winds provided us with a launch window, containing August 26 throughSeptember 5, wherein stratospheric zonal wind speeds are low enough in Vanscoy to facilitate alaunch. These campaigns also allowed for the development of the first Canadian balloon-borneFourier transform spectrometer in 30 years, which we call the University of Toronto’s Fouriertransform spectrometer (U of T FTS). The electronics and software development of the U of TFTS will be described, and the first spectrum from the MANTRA 2004 balloon flight will beshown. The U of T FTS also participated in a ground-based intercomparison campaign inToronto with the Toronto Atmospheric Observatory Fourier transform spectrometer (TAO-FTS)and the Portable Atmospheric Research Interferometric Spectrometer for the Infrared (PARIS-IR). The resolutions of these three instruments are significantly different, allowing us toinvestigate the effect of resolution on the retrieval of total columns of O3, HCl, N2O and CH4,and determine what parameters most affect the retrievals. The two lower-resolution instruments(PARIS-IR and the U of T FTS) were found to measure 4-day average total columns of O3, HCl,N2O and CH4 to within 3.5% of the TAO-FTS total columns. The largest errors were producedby the total column retrievals of the stratospheric species (O3 and HCl). In order to achieve this3.5% agreement for the stratospheric species, the instrument line shape of the U of T FTS andPARIS-IR instruments had to be taken into account.
