ECHO

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. Currently, ECHO contains metadata for over 2,400 data collections comprising 81 million individual data granules and 26 million browse images. 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. ECHO also has a services registry for community-developed search services and data services.

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. The value of these resources increases as the potential to exchange and interoperate increases.
