  1. NASA Support for WTF-CEOP May 2006 Ken McDonald, NASA Yonsook Enloe, SGT Inc.

  2. CEOP/CEOS Collaboration • CEOP Scientists need efficient access to satellite data, model output data, and field data • CEOP science community lack advanced tools to access the satellite data with the services needed to support data integration • CEOP Program initiated a discussion with CEOS WGISS to ask for assistance in solving this problem • CEOP science community and CEOS WGISS information technologists have teamed together to remove IT barriers to access and use satellite data for CEOP data integration

  3. Data sources • Data location • Standalone physical location • Distributed sites reference by links • Data types • Model output data • Insitu data • Satellite data • Services • Metadata keyword search • Data value search • File format translation • Reprojection • Regridding • Data Interpolation Integrated datasets Multiple files from individual member datasets Intercomparison Of Integrated Datasets Spatial Temporal rectification Spatial rectification CEOP Data Integration

  4. CEOP Satellite Data Server • CEOP science community is using the OPeNDAP enabled clients and servers to analyze the field data and model data • CEOP science community had difficulty using satellite data because of the lack of tools • NASA’s Satellite Data Server prototype was developed that demonstrated OPeNDAP client (Grads) access to the WCS server capabilities. • Prototype was demonstrated at CEOP Implementation Planning meeting and previous WGISS meetings.

  5. Grads Client Other OPeNDAP Clients OPeNDAP Request Translator Default georectification CF Attrubute Constrtuction Custom Requests (future) Grads-DODS Server (GDS) Field Data Model Output Satellite Data Server WCS Client NWGISS WCS Standard Functions e.g. subsetting Standard Functions e.g. subsetting Custom Functions (Grads) Satellite Data, Swath and Grid

  6. Integration of Satellite and Model Data

  7. Continuing Support • Using the prototype as a basis, the NASA team (McDonald/GSFC, Di/GMU, Enloe/SGT, Holloway/OPeNDAP) proposed to NASA’s Advancing Collaborative Connections for Earth-Sun System Science (ACCESS) Program. • NASA team awarded 2 year ACCESS funding to develop the Satellite Data Server with an optional 3rd year. • A second proposal to develop a gateway that would make OPeNDAP servers accessible to OGC clients was partially supported and merged with this effort - added two additional team members (Domenico/Unidata, Rutledge/NOAA-NCDC).

  8. Status and Plans • Held kick-off meeting with combined team in March • Finalized work plan for both gateways • Satellite Data Server will be developed as proposed, allowing the CEOP scientists to inter-compare satellite data with model output data and field data • Plan to deploy the Satellite Data Server at JAXA and other sites with satellite data of interest to the CEOP community • OGC/Geoscience Gateway will focus on catalog services - WCS access will be addressed with 3rd year funding • Paper describing the Satellite Data Server and the OGC/Geoscience Gateway accepted for the IGARSS 06 conference

  9. CEOP SDS Architecture

  10. OGC/Geoscience Gateway

  11. OPeNDAP & ECHO • OPeNDAP and ECHO team are working together to provide direct search and access to ECHO via OPeNDAP enabled clients (e.g. Matlab) using ECHO’s web services. (Interim prototype demoed at the DSTT presentation on Tuesday.) • ECHO search query implemented as an ECHO web service, using ECHO’s 8.0 web service APIs. • A demo of matlab searching and accessing ECHO via the ECHO search query implemented as a web service is scheduled for July. • Future work could include other OPeNDAP enabled clients directly searching ECHO.

  12. WIST Demonstration • WIST is the comprehensive search tool for ECHO. Comparable functionality with EDG • Some test CEOP metadata (2 collections and 4 granules) ingested into a test ECHO system. Currently there are 10,000 satellite products of interest to CEOP. Could have over 1M products in the future. • Demo will search for CEOP metadata ingested into a test ECHO system.
