NEW FIVE-YEAR APPOINTMENTS ANNOUNCED

Last week five NCAR scientists--Rainer Bleck, Gerald Grams , Thomas Holzer,Katsuyuki Ooyama, and Raymond Roble--accepted five-year appointments at NCAR. Thenew five-year appointees have differing scientific interests, arrived at by differentroutes, as the profiles below illustrate.

Rainer BZeck

"I enjoy teaching because it helps toput things in order," says Rainer Bleck of theSmall-Scale Analysis and Prediction Project."When I present my current work to studentswho are less specialized, I often get some newinsight. I wouldn't enjoy teaching some sub-ject that I wasn't working with on my own,however."

Rainer will get to do more teaching thisfall at the University of Miami in Florida,where he will be an associate professor on rleave from NCAR. His talents as a theoreticalmeteorologist are much in demand.

"In a way," he says, "it runs in thefamily. My father is a forecaster with theGerman weather service. In Germany more than in the United States, forecasting

isn't generally regarded as 'scientific.' The popular view is that it's more akinto astrology. But I became interested in meteorology because I was close enough to

it to see that it is a science."

Rainer obtained his master's degree in the department of theoretical meteorol-

ogy of the Freie Universitat in Berlin in 1964. From there he went to Pennsylvania

State University, where he studied under Edwin Danielsen. He came to NCAR in 1967and completed his Ph.D. thesis while working here. The topic was isentropic airtrajectories--the theory of predicting the future whereabouts of a parcel of air(something on a scale of several kilometers in diameter) by following the propertiesthat are conserved as the air moves about, such as the energy or entropy.

NCAR Staff Notes 3/28/75

Rainer recalls that he, Ed Danielsen, and Philip Haagenson served as a sortof "meteorological task force" within NCAR's chemistry department from 1967 to 1971.In 1971, Rainer started working with the synoptic meteorology group under ChesterNewton, and it was then that he began to work with Mel Shapiro on numerical weatherprediction using isentropic coordinates. In 1972, NCAR's Technology AdvancementAward was given to Rainer, Mel, Dave Fulker, and Jordan Hastings for their coopera-tive effort in developing, testing, and applying objective isentropic analysisschemes for the improvement of numerical forecasting.

In isentropic modeling, the atmosphere is mapped on surfaces of constantentropy (constant potential temperature) rather than on surfaces defined by constantpressure or height, as is commonly done. With entropy used as a vertical coordi-nate, grid points for model calculations are clustered in regions of frontal weatheractivity, resulting in forecast maps of higher resolution than those produced byconventional coordinate models. At Miami, Rainer hopes to do isopycnic ocean mod-eling--mapping the ocean on surfaces of constant density in a fashion analogous tothe isentropic modeling he developed at NCAR.

Gerald Grams

Gerald Grams is a pioneer in the use oflaser radars to probe the atmosphere. "When Iwrote my thesis at MIT," he says, "the laser wasbrand-new. I've sort of grown up with the field,trying to balance instrument development, fieldwork, and theoretical work in interpreting laserradar echoes from aerosol layers in the atmosphereand in calculating the response of the atmosphereto the presence of those aerosols layers."

Gerry graduated from Mankato State Collegein Mankato, Minnesota, in 1960. "When I begancollege, I thought of becoming a high school shopteacher and possibly teaching some math courses.

s Then I began to study math and physics, and myinterest in science snowballed." He taught highschool math and physics for a year, then went toMIT on a Ford Foundation fellowship in meteorol-ogy. There he worked with Giorgio Fiocco, obtain-ing the first laser radar observations of the

stratospheric aerosol layer. The observations began in 1964, shortly after theeruption of Mt. Agung on the island of Bali in the south Pacific, and continuedthrough most of 1965. Gerry's thesis and his subsequent studies have been used bya number of researchers in establishing the natural or background variability ofthe stratospheric aerosol layer.

(continued)


After obtaining his doctorate in 1966, Gerry was a research associate at MITin the Department of Geology and Geophysics, using laser radar to detect mesosphericaerosols (at altitudes of 60 to 80 km above sea level). In 1967 he began workingfor the NASA Electronics Research Center in Cambridge, Massachusetts, developinginstruments to measure atmospheric parameters (winds and temperatures, for example)that can be derived from the shape of the spectrum of the light scattered from asingle-frequency laser beam. The NASA center was closed in mid-1970, and Gerrycame to NCAR, where he has continued work on the development of laser sensors andthe study of the optical properties of atmospheric aerosols. Instruments he hasdeveloped at NCAR, in collaboration with Clyde Wyman, include an airborne laserradar, with which he carried out a collaborative study of stratospheric aerosolswith researchers at the University of Wisconsin in 1971, and an airborne laserpolar nephelometer. The nephelometer, now in use aboard the NCAR Electra aircraft,measures the angular variation of the intensity of scattered light.from aerosolssampled in the flight path to determine their size distribution and refractiveindexes.

Gerry is currently working with Giorgio Fiocco, who is now at the Universityof Rome, Italy, and with NCAR's James Coakley (Climate Project) on calculations ofthe climatic effect of aerosols, using data on aerosol optical properties, some of

* which were obtained in studies that used the laser instruments. Gerry has alsobeen working with Edward Patterson (Advanced Study Program) on the determination ofaerosol optical properties using both conventional techniques and new devices andprocedures under development at NCAR.

In the field of instrument development, Gerry is working with Clyde Wyman andEd Patterson to develop an automatically operated polar nephelometer to be flownaboard a U-2 or similar high-altitude aircraft to obtain in situ stratosphericaerosol measurements. The miniaturized nephelometer will use a small tape cassetteto record data on the light-scattering properties of the aerosol particles as afunction of time. Another project is a "next-generation" laser radar system, nowbeing interfaced with a minicomputer for real-time data reduction and analysis.Data will be displayed in forms that are easily interpreted by meteorological work-ers without special training in the laser radar field.

"NCAR has just about everything we need," Gerry says. "From the computer tothe machine shop to the aviation facility--it's very unusual to have such an arrayof support available. And there have been a large number of scientists at NCAR andat the universities whose interests have helped to shape the direction of ourresearch."

Thomas Hoizer

"It may be a dangerous thing these days togo without publishing a paper for a year or so,"Tom Holzer says, "but that's what George Reid andI found we had to do when we started looking atthe problem of magnetospheric substorms." Reid,of the Aeronomy Laboratory at the National Oceanicand Atmospheric Administration, collaborated with

S; Tom recently in proposing a theoretical model toexplain the motion of magnetic flux inside theearth's magnetosphere. "When we began to thinkabout it, we realized that we understood nothing,and we weren't happy with most of the theoriesthat had been put forward. It took us between sixmonths and a year just to find the starting point.It's easy enough to write down all the equationsthat apply," Tom says, "but when you're finished,you have an insoluble system of equations. In

' ,order to find real solutions, physicists must goi / outside of the equations and make simplifying

assumptions. Then they must prove that whatthey've taken out is really unimportant and that what remains suffices to explainthe phenomenon in question. We think the risk we took in thinking our problemthrough from beginning to end is paying off--our model of the response of the mag-netosphere-ionosphere system to processes occurring at the daytime side of theearth's magnetic-field boundary is a simple model, which is a qualitative advance.And we've shown that the model's quantitative predictions accord with satelliteobservations."

Tom works on magnetosphere-ionosphere problems at NCAR's High Altitude Obser-vatory (HAO). While an interest in solar physics may seem logical enough for anative of sunny southern California, Tom says, "On the contrary. It took me off thebeach." After graduating from Pomona College with a B.A. in physics in 1965, hebegan studying oceanography at the Scripps Institution in La Jolla. From there itwas a swift evolutionary climb out of the water and up the beach to the Universityof California at San Diego, where Tom continued his graduate work in the departmentof applied physics and information science. "I really got interested when I beganto study space physics and astrophysics under Peter Banks and Ian Axford," he says,"My thesis was written under Banks and Axford on the subject of stellar winds andrelated flows. Fluid-like flows are important on planetary, stellar, and evengalactic scales. Part of the thesis was a quantitative underpinning for Axford'spostulation of a 'polar wind,' an outward flow of thermal particles from the regionssurrounding the earth's magnetic poles." After receiving his Ph.D. in 1970, Tom


spent a year in England studying the interaction of the solar wind with the inter-stellar medium. He then spent two years at NOAA's Aeronomy Laboratory in Boulderas a National Research Council Resident Research Associate. He joined HAO in 1973.

Like many HAO scientists, Tom is a lecturer in the Astro-Geophysics departmentat Colorado University and serves on students' thesis committees. He also has con-tinued his collaborations with workers at NOAA and NASA. "I think that the bestthing about working at HAO is the opportunity to learn from and interact with sci-entists in fields that are related to my own. The level of intellectual stimula-tion there is very high," Tom says.

Katsuyuki Ooycna

Working with the GATE Project represents anew emphasis for Katsuyuki (Victor) Ooyama. Aphysics major at Tokyo University, he worked atthe Japan Meteorological Agency before coming tothe United States in 1955 for graduate studies atNew York University (NYU). After receiving his

* Ph.D. in meteorology in 1958, he stayed on at NYU,first as a research associate and, after 1962, asa faculty member. During this time he concen-trated on numerical modeling of hurricanes, receiv-ing the Meisinger Award of the American Meteoro-logical Society in 1969. Once the basic hurricanemodel was built, Vic's interest shifted to theparameterization of cumulus convection, whichmust be better understood to explain the origin ofhurricanes. He joined the GATE Project in 1973 andbegan to pursue that problem. "Before I came toNCAR," he says, "my work was mostly on the theoret-ical side. This was a good chance to look atthings from the other side, and that's why I'm here.What I am hoping is to be able to incorporate an understanding of the physical pro-cesses involved into the formal mathematical expressions of a theoretical model."

While the data collected in Dakar last summer are undergoing preliminary pro-cessing, Vic is preparing and testing the computer program he will use in his anal-ysis,. The validated data will become available beginning some time next year, andhe believes that the scientific analysis will continue until about five years fromnow. "I am anxious to see the data," he says, "because it's hard to tell at thispoint how much we will learn from GATE. How far we can go depends on the qualityof the data and to what extent they are representative of the tropics. My immedi-ate goal is to get as much information as possible out of the data and construct anumerical model to test new ideas on cumulus parameterization, then eventually,when such a model is perfected, to apply it to the General Circulation Model, Andat some time in the future, I'd like to return to more direct work on the hurricaneproblem."

Raymond Roble

Ray Roble's work in dynamic modelingof the ionosphere and of the circulation of

the upper atmosphere involves a good deal ofcooperation with other scientists in thesame field. For example, he and BobDickinson (Upper Atmosphere and Climateprojects) have collaborated to developmodels of upper atmospheric circulation.Ray is interested in the general meteorol-ogy of the upper atmosphere (about 100 km .and higher) and its response to solar k

flares and auroral activity, as well asionospheric physics and the interactionbetween neutral and ionized gases in thethermosphere. His own contribution tothese studies is primarily theoretical; forthe actual measurements he relies on the work of other scientists. "These measure-ments are difficult and expensive," he says, "and can only be taken with largeground-based systems like the incoherent scatter radar operated by MIT's LincolnLabs at Millstone Hill, Massachusetts, and the one at Arecibo, Puerto Rico; withground-based optical systems; or with satellites. So I have to go to my universitycolleagues who get the data, which I then help to interpret and with which I, inturn, update and interpret my models. I've also used some satellite data, like themeasurements of how rapidly stars or the sun fade at satellite 'sunrise, and 'sun-set' because they can be an indication of upper atmospheric properties."

Ray received all his degrees at the University of Michigan, with interveningstints in the Navy and in industry. His B.S. was in physics, his M.S. in mechani-cal engineering, and his Ph.D. in aeronomy (1969). He's been at NCAR since then,first as a Postdoctoral Fellow in the Advanced Study Program, then as a member ofthe Dynamics Department under the old Laboratory of Atmospheric Science structure,and finally as a member of the Upper Atmosphere Project since its formation twoyears ago.

His main interest remains the circulation of the upper atmosphere, but it hasexpanded more recently to include some aspects of interaction with the slightlylower atmosphere. His present research derives from the fact that energy enteringthe atmosphere during auroral processes very strongly controls the large-scalecirculation of the thermosphere. "Our progress over the next few years," he says,"depends on how well we are able to define the sources of heat and momentum involv-ed. 1

HAO INSTRUMENT PROPOSAL CLEARS NASA HURDLE

The proposal made by a team of investigators including scientists from NCAR'sHigh Altitude Observatory (HAO) for a solar coronagraph/polarimeter to be flown onthe NASA Solar Maximum Mission in .1978 has been selected for further instrumentdefinition study by NASA. It is one of 13 instrument proposals, of which eightwill be chosen later this year to fly on the NASA satellite mission.

Robert MacQueen, principal investigator, and Lewis House, principal scientist,both of HAO, made the proposal with co-investigators George Dulk, chairman of theColorado University Astro-Geophysics Department; Hermann Schmidt of the Max PlanckInstitut in Munich, Germany; Kevin Sheridan of the Commonwealth Scientific andIndustrial Research Organization Division of Radiophysics, Sydney, Australia;William Wagner of Sacramento Peak Observatory, Sunspot, New Mexico; and HAO sci-entists Martin Altschuler, Richard Hansen, Roger Kopp, Charles Querfeld, andCharles Ross.

The instrument they have proposed will yield observations that will enablesimultaneous measurement of coronal electron density and magnetic field on timeintervals sufficiently small to permit investigation of the detailed behavior ofcoronal transients--the vast outward-moving "bubbles" of mass and energy observedby the HAO coronagraph aboard Skylab.

GRAPHICS: ASSIGNMENTS IN AND OUT

The Graphics Group's workload information is printed each week in Staff Notesto assist scientists and other staff in planning ahead for graphic services. Thesereports are meant to be informative at a glance, and the Graphics staff welcomessuggestions to improve their usefulness.

The backlog figure represents both high and low priority work, including jobsthat require from half-an-hour to several weeks for completion. Work is done on afirst-come, first-served basis, but priority judgments are made, taking into accountthe size of the jobs.

Minor corrections to completed jobs are usually done on the same day that theyare submitted.

With the current heavy workload, scientists should allow about two-and-a-halfweeks for completion of graphip work from the time of submission; after the artworkis completed additional time is needed by the Printshop and Photographics Lab toproduce requested slides and glossy prints.

As of March 25: 64 pieces of artwork completed for 22 scientists since last report;128 pieces of artwork requested by 26 scientists since last report; 247 pieces ofartwork backlogged as of March 25. Estimated starting date for new work: April 9.
