The document discusses current and future systems for air quality information. It describes how current data is siloed across different providers and formats. A future integrated system is proposed where data is exposed through portals, mediators provide uniform access, and analysts can program services to create customized products from the distributed data resources. The infrastructure could be provided by ESIPFed and shared responsibility models between data providers and integrators.

1. Current Air Quality Information ‘Ecosystem’ (Draft for Feedback) AQ information includes emissions , ambient & satellite data and model outputs The distributed data are produced and provided by agencies , mostly through portals Providers have different access protocols , formats, and information usage conditions This lack of interoperability causes the under-utilization of the rich data resources

2. Future Integrated AQ information System (Draft for Feedback) Data are maintained by custodians and exposed through ‘portals’ Mediators uniformly ‘wrap’ data and provide processing services Analysts program the services to create application-specific products Responsibility is shared among data providers and mediator/ integrators ESIPFed can provide the infrastructure and tools for the AQ info system DataMart VIEWS NEISGEI AIRNow AQMod DAACs ASOS NEI Emission IDEA GASP Missions WeaMod Forecast GloMod FireInv Data Federation Distributed, Virtual, Uniform AQ Forecasting AQ Compliance Status and Trends Network Assess.

4. DataFed Description DataFed Vision Better air quality management and science through by effective use of relevant data DataFed Goals Facilitate the access and flow of atmospheric data from provider to users Support the development of user-driven data processing value chains P articipate in specific application projects Approach: Mediation Between Users and Data Providers DataFed assumes spontaneous, autonomous emergence of AQ data ( a la Internet) Non-intrusively wraps datasets for access by web services WS-based mediators provide homogeneous data views e.g. geo-spatial, time... End-user programming of data access and processing through WS composition (limited) Applications Building browsers and analysis tools for distributed monitoring data Serve as data gateway for user programs; web pages, GIS, science tools DataFed is currently focused on the mediation of air quality data

5. Anatomy of a Wrapper Service: TOMS Satellite Image Data Given the URL template and the image description, the wrapper service can access the image for any day, any spatial subset using a HTTP URL or SOAP protocol: Wrapper classes are available for geo-spatial (incl. satellite) images, SQL servers, text files,etc. The mediator classes are implemented as web services for uniform data access, transformation and portrayal. src_img_width src_img_height src_margin_right src_margin_left src_margin_top src_margin_bottom src_lon_min src_lat_max src_lat_min src_lon_max Image Description for Data Access: src_image_width=502 src_image_height=329 src_margin_bottom=105 src_margin_left=69 src_margin_right=69 src_margin_top=46 src_lat_min=-70 src_lat_max=70 src_lon_min=-180 src_lon_max=180 The daily TOMS images reside on the FTP archive, e.g. ftp://toms. gsfc . nasa . gov /pub/ eptoms /images/aerosol/y2000/ea000820.gif URL template: ftp://toms.gsfc.nasa.gov/pub/eptoms/images/aerosol/y[yyyy]/ea[yy][mm][dd].gif Transparent colors for overlays RGB(89,140,255) RGB(41,117,41) RGB(23,23,23) RGB(0,0,0)

12. Aerosol Event Catalog: Web pages Catalog of generic ‘web objects’ – pages, images, animations that relate to aerosol events Each ‘web object’ is cataloged by location, time and aerosol type.

13. Distributed Responsibility in OpenDAP The data lies with the data providers The data access protocol lies with OPeNDAP Application programs with the developers (Matlab, .. Excel…) Data discovery with the GCMD and NVODS Distributed Responsibility DataFed(??)
