ECHO (EARTH OBSERVING SYSTEM (EOS) CLEARINGHOUSE)
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 was built by NASA's Earth Science Data and Information System (ESDIS).
Enable broader use of NASA's EOS data by allowing users to more efficiently search and access data and services; thus increasing the potential for interoperability with new tools and services.
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.
