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. ECHO 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.

The ECHO metadata model focuses on data discovery and includes two sets of recommendations: Mandatory Fields and Recommended Fields. These recommendations are listed here along with xPaths to the recommended concepts in many metadata dialects.

ECHO for Data Discovery - Mandatory

This recommendation includes the required fields from Section 4.2 of the ECHO Data Partner's User Guide (Version 10.7).
