EOS Clearing House (ECHO)

NASA's Earth Science Data Information Systems (ESDIS) program is responsible for providing access to Earth Observation data and services to an ever-growing user community. That user community includes Earth Scientists, Educators, other government agencies, decision makers and citizens in general. Access the ECHO holdings using the Reverb Client.

Welcome to the ECHO Community

The NASA-developed Earth Observing System (EOS) Clearing House (ECHO) is a spatial and temporal metadata registry and order broker built by NASA's Earth Science Data and Information System (ESDIS) 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. For examples of how NASA's Earth science data is helping scientists understand the complexities of our Earth, visit the articles under Sensing our Planet.
