The NASA-developed Earth Observing System (EOS) Clearinghouse (ECHO) is a spatial and temporal metadata registry that enables the science community to more easily use and exchange NASA's data and services. ECHO's main objective is to enable broader use of NASA's EOS data. It allows users to more efficiently search and access data and services and increases the potential for interoperability with new tools and services. The value of these resources increases as the potential to exchange and interoperate increases. ECHO has been working with other organizations to provide their Earth science metadata alongside NASA's for users to search and access. ECHO stores metadata from a variety of science disciplines and domains, including Climate Variability and Change, Carbon Cycle and Ecosystems, Earth Surface and Interior, Atmospheric Composition, Weather, and Water and Energy Cycle.
NASA's Earth science data has already proven itself to be extremely useful in understanding the planet Earth as an integrated system. To help science communities that need data from multiple organizations and multiple disciplines, ECHO provides a uniform view of NASA's data. It allows users to more efficiently search and access data and services and increases the potential for interoperability with new tools and services.

LPDAAC EOS Data Holdings Removed from EDG
In conjunction with the migration of data access from the EOS Data Gateway (EDG) to the Warehouse Inventory Search Tool (WIST), LP DAAC EOS data holdings will be removed from EDG no earlier than October 8, 2008. Currently, and after the removal from EDG, the LP DAAC data holdings are available through WIST.

EOSDIS Evolution
The Evolution of EOSDIS vision emphasizes increased end-to-end data system efficiency and operability; increased data usability; improved support for end users; and decreased operations costs. Due to concurrent operations, the transition of operations to newer systems is being carried out incrementally. ECHO’s Warehouse Inventory Search Tool (WIST) is replacing the legacy system , EOS Data Gateway (EDG), as the primary means of accessing EOSDIS and other Earth science data holdings archived at the EOSDIS data centers.

EDG Retirement
Culminating many dignified years of service to the Earth Science community, the EOS Data Gateway (EDG) will be officially retired on February 28th, 2009. ECHO’s Warehouse Inventory Search Tool (WIST) is now the primary means of accessing EOSDIS and other Earth science data holdings archived at the EOSDIS data centers.

Landsat products available through WIST
Beginning February 27, 2009, Landsat 7 Enhanced Thematic Mapper Plus (ETM+), Landsat 1-5 Multispectral
Scanner (MSS), and Landsat 4-5 Thematic Mapper (TM) standard data products are available through the
NASA Warehouse Inventory Search Tool (WIST). Newly acquired Landsat 7 ETM+ and Landsat 5 TM images
with less than 40 percent cloud cover are automatically processed. These, plus an additional 70,000
Landsat 7 ETM+ scenes, are available for immediate download. Images that are currently unavailable
can be processed at no charge upon request through WIST. Please Note: Landsat 5 TM and Landsat 7 ETM+
data may take 1 to 3 days for processing. Landsat 1-5 MSS, Landsat 4 TM and some Landsat 5 TM data may
take up to twelve weeks to process due to a high volume of requests or quality of the data.
Please contact LP DAAC User Services for more information about using WIST.
For any inquiries regarding Landsat data, please contact USGS Customer Service and reference your order number.
