2. NASA ESD Status • 16 EOS satellites successfully deployed, 3 more to go • Future mission profile looks uncertain, appears to ramp down • Earth science appears to be losing ground in NASA’s overall priority list • Focus currently on six interdisciplinary science areas: • Atmospheric Composition • Carbon Cycle and Ecosystems • Water and Energy Cycle • Climate Variability and Change • Weather • Earth Surface and Interior • The fundamental question: “How is Earth changing and what are the consequences for life on Earth?” S e p t e m b e r 7 , 2 0 0 6

3. New CEOS InitiativesCourtesy Ken McDonald, ESDIS • Coordinated Enhanced Observing Period (CEOP) is a major initiative of the Integrated Global Observing Strategy (IGOS) Water Cycle Theme • CEOP seeks to establish an integrated global observing system for measurement, understanding, modeling and predicting water and energy cycles • CEOP has established 35 reference sites and multiple enhanced observing periods where they are collecting: • In-situ Data • Time Series and Gridded Model Output Data • EO Data From JAXA, NASA, ESA and EUMETSAT • Collections of each data type are being archived at NCAR, Max Planck Institute, and Univ. of Tokyo, respectively S e p t e m b e r 7 , 2 0 0 6

4. CEOP / CEOS Collaboration • CEOP Scientists need efficient access to satellite data, model output data, and field data • CEOP science community needs advanced tools to access the satellite data with the services needed to support data integration • CEOP Program initiated a discussion with CEOS Working Group on Information Systems & Services (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 S e p t e m b e r 7 , 2 0 0 6
