1. Building an Air Quality Community Infrastructure and Connecting with the GEOSS Common Infrastructure Stefan Falke, Rudolf Husar, Erin Robinson, David McCabe, Frank Lindsay GEO-VI Air Quality Meeting November 18, 2009

2. Traditional Project Approach Data Do something with the data (add value) Generate Product Deliver Product to Customer Closed System 2

3. Making Project Contributions Reusable Sharing/Exchanging with more than the primary customer Data Do something with the data (add value) Generate Product Deliver Product to Customer Provide Website Access (manual) Provide web service access Provide access to processing/analysis/value-adding services 3

4. 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 PM 2.5 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 storms Smoke from forest fires Urban/industrial haze System requirements Direct broadcast receiving station for satellite data Trajectory model Regional meteorological forecast model output Algorithms to derive aerosol optical depth or related parameters Surface mass aerosol monitors System flexibility Easily adaptable to other regions of the globe Easy to modify to input other satellite data Benefit - Enable improved mitigation of health effects caused by episodes of poor air quality Infusing satellite Data into Environmental Applications (IDEA) Al-Saadi et. al., September 2005, Bulletin of American Meteorological Society http://www.star.nesdis.noaa.gov/smcd/spb/aq/ 4

8. GEO-VI Plenary Meeting Washington, DC November 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 8 GEO Task AR-09-02b DLR Giovanni Datafed Others OGC WMS OGC WCS Plan is to have a beta version of the ACP by September 2010 OPeNDAP DLR Giovanni Datafed Others DLR Giovanni Datafed Others Data Access Gateways Visualization Tools Processing/Analysis Tools Initial focus on air quality but plan is to server broader community (climate, strat. O3) GEOSS User Contributed Content Users Contextual metadata

9. Many other AQ related projects… List of US projects from the EPA Data Summit: http://wiki.esipfed.org/index.php/AQ_Data_Systems_and_Processing_Centers Start of an international compilation of project descriptions: http://wiki.esipfed.org/index.php/GEOSS_Relevant_AQ_Projects 9

10. A GEOSS Vision for Connecting Air Quality Projects 10

11. 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

12. 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

13. Project C provides a web services new data from its work Project C 13

14. New Project A new project uses services from projects A, B and C to meet its objectives 14

19. 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 19
