  2. Enforcing Standards Atmospheric Composition Informing the Public Hemispheric Transport Science & Education Regulatory Analysis Real-time Service Policy Assessment Air quality community spans efforts • Monitor the atmosphere (surface, satellite and aerial systems), • Model future atmospheric behavior and air quality conditions, • Measure and estimate emissions of pollution and pollution forming gases and particles, • Combine those information with socio-economic data for decision making analyses.

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

  5. Interoperability Challenges • Standalone-project-oriented approaches • Multiple interoperability standard implementations • Required tailored implementation of standards “The user cannot find the data; If he can find it, cannot access it; If he can access it, ; he doesn't know how good they are; if he finds them good, he can not merge them with other data” The Users View of IT, NAS 1989

  6. Air Quality & Health Applications

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

  8. Project A 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

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

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

  11. SOA Actions Broker Publish– ISO 19115,19119 Find – OpenSearch BindOGC W*S User Provider The data reuse is possible through the service oriented architecture of GEOSS.

  12. Community/Provider Catalogs Data Access Service Data Providers Metadata ISO 19115/19119 subset for Geospatial Data Data Protocol WMS, WCS (netDCF CF) + conventions

  13. GEOSS CSR Data Access Service • Registration Specifies: • Where the records are located • Metadata standard • Harvest periodicity

  18. HTAP Data Network • FZ Juelich server offers 1000+ HTAP model ‘datasets’ • WCS–netCDF–CF Standard Protocol • FZ Juelich & WashU Co-develop connectivity software Clients can access any HTAP model ‘datasets’ for browsing, comparison, statistical…processing DataFed Giovanni YOUR client software can also access any HTAP model ‘datasets’Perform your types of analyses The data the tools and the methods are shared to the Community through the AQ CoP So, participants of this project automatically become members of AQ CoP

  19. CEOS 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 GEO Task AR-09-02b User Contributed Content Users Contextual metadata GEOSS Data Access Gateways Visualization Tools Processing/Analysis Tools Beta version of the ACP by September 2010 OGC WMS DLR DLR DLR OPeNDAP Giovanni Giovanni Giovanni Initial focus on air quality but plan is to server broader community (climate, strat.

  22. Summary and Issues • The air quality interoperability efforts have found some success in using existing web standards to achieve a base level of interoperability • Many challenges remain spanning technical issues in making standards work for air quality uses to organization issues in achieving agreement among air quality-specific conventions to standards • As the community gains experience in how to implement and tailor the standards they will develop best practices • The interoperability efforts described in this abstract have focused on OGC standards. However, there is a desire to evaluate the applicability of other web standards for air quality systems, in particular OPeNDAP.

Air Quality Community Infrastructure Data web service metadata registrations General search and use of GEOSS data and services GEOSS Common Infrastructure Air Quality Community Catalog Users AQ-specific search and use of GEOSS data and services DataFed EDAC SEDAC Giovanni NGC ESA Data Providers AIP-2 Workspace: https://sites.google.com/site/geosspilot2/air-quality-and-health-working-group

  26. Next Steps: • Continue to work with AQ community to improve the AQ-specific sections needed for sharper discovery • Work with AQ data providers to register their services in AQ Community Catalogs • Extend metadata with unstructured user-contributed content through DataSpaces • Use the GEOSS AQ CoP to help coordinate activities

  27. Air Quality Community Interoperability Efforts(not comprehensive) • GEO AQ CoP: Working to connect various AQ networking activities • GEOSS AIP-3: The GEOSS Architecture Implementation Pilot (AIP) develops and deploys new process and infrastructure components for the GCI and the broader GEOSS architecture • HTAP: The HTAP network aims to facilitate seamless access to distributed HTAP model data, easy connectivity of data processing components through standard interfaces, and provide a set of basic tools for data processing, integration, and comparisons. • CEOS AC Portal: The AC Portal is being developed to provide access, tools, and contextual guidance to scientists and value-adding organizations in using remotely sensed atmospheric composition data • CyAir: Contributions to the planning, development, maintenance and coordination of systems to help the air quality community better utilize air quality related information

  28. Infusing satellite Data into Environmental Applications (IDEA) 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 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 http://www.star.nesdis.noaa.gov/smcd/spb/aq/ Al-Saadi et. al., September 2005, Bulletin of American Meteorological Society
