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:

1. Atmospheric Composition2. Carbon Cycle and Ecosystems3. Water and Energy Cycle4. Climate Variability and Change5. Weather6. Earth Surface and Interior

The fundamental question: “How is Earth changing and what are the consequences for life on Earth?”

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

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

CEOP scientists desire direct access to full range of satellite data products and services

• Latest versions of products• Flexible access to data services

There is widespread and growing use of Open Geospatial Consortium (OGC) specifications by satellite data providers

NASA developed a CEOP Satellite Data Server prototype that demonstrated OPeNDAP client (Grads) access to the OGC-WCS server capabilities

Using the prototype as a basis, the NASA team proposed to NASA’s Advancing Collaborative Connections for Earth-Sun System Science (ACCESS) Program

• 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 merged with this effort

• Added two new team members (Domenico/Unidata, Rutledge/NOAA-NCDC)

NASA GES DISC created GIOVANNI — an on-line data visualization and analysis infrastructure, featuring:• Access to data from multiple remote sites as well as local

sites.• Server-side temporal and spatial subsetting.• Server-side processing.• Support for multiple data formats including Hierarchical Data

Format (HDF), HDF-EOS, network Common Data Form (netCDF), GRIdded Binary (GRIB), and binary.

• Support for multiple plot types including area, time, Hovmoller, and image animation.

• Support for outputting data in ASCII format in multiple resolutions.

• Multi-parameter intercomparisons• Easily configurable to support customized portals for

measurements-based projects or disciplines.

SIVO headed by Michael Seablom• A program to support NASA modeling programs, including

development of software environments for collaborative research among a range of modeling and assimilation activities

• Has a formal interface into the multi-agency Earth System Modeling Framework (ESMF)

• Maintains publicly available WMS servers of model and satellite data sets, including the MAP ’06 Program

• Provides oversight of:– NASA’s Earth Observatory Team (earthobservatory.nasa.gov)– NASA’s Scientific Visualizations Studio (svs.gsfc.nasa.gov)

Emphasis on the use of OGC standards & tools
