A joint NASA-NOAA-EPA initiative:

Objective - Prototype a near-real-time MODIS trajectory forecast product using MODIS direct broadcast aerosol optical depth over CONUS.

Goal - Improve accuracy of next day PM2.5 Air Quality Index (AQI) by providing pseudo-synoptic aerosol observations and trajectory forecast during large aerosol events.

• Provides forecast guidance for surface air quality (PM2.5)Dust stormsSmoke from forest firesUrban/industrial haze

• System requirementsDirect broadcast receiving station for satellite dataTrajectory modelRegional meteorological forecast model outputAlgorithms to derive aerosol optical depth or related

parametersSurface mass aerosol monitors

• System flexibilityEasily adaptable to other regions of the globeEasy to modify to input other satellite data

Benefit - Enable improved mitigation of health effects caused by episodes of poor air quality

GEO-VI Plenary MeetingWashington, DCNovember 17-18, 2009

Atmospheric Composition Portal

Objectives

• Provide access, tools, and contextual guidance to scientists and value-adding organizations in using remotely sensed atmospheric composition data, information, and services

• Help foster interoperability and application of atmospheric composition data, information and services worldwide

• Start with DLR and NASA, work with partners in CEOS and the broader AC community in advancing the AC Portal

A GEOSS Vision for Connecting Air Quality Projects

10

Project A combines multiple data sources to generate near-real time information for the public

Project A provides web service interfaces to some of its data and information

Project A

11

Project B analyzes surface and satellite data in support of regulatory analysis and provides web services to their analysis output and analysis tools

Project B

12

Project C provides a web services new data from its work

Project C

13

New Project

A new project uses services from projects A, B and C to meet its objectives

Ways to participate

Community Building • Share your interests and project contributions (like this meeting)• Use ESIP and other air quality communities of practice to advance your project objectives (e.g.,

‘built-in’ testers, users…)• Help define the GEOSS GCI and/or Community of Practice

Enhance the Information Infrastructure• Become a ‘node’ on the air quality interoperability network• Learn best practices in implementing standards for sharing your project data and tools• Participate in (and shape) the GEOSS Architecture Implementation Pilot • Use the AQ Community Information Architecture (register your services in GEOSS, find

information resources useful for your project)• Participate in the development of air quality information networks

Collaborate on AQ Science and Research Projects• Define projects that leverage expertise and capabilities across organizations• Document how data, information and capabilities are shared in the project
