NASA Common Metadata Repository (CMR) is a high-performance metadata system that catalogs Earth science data collections, granules, variables, services, and tools across NASA data centers. It provides REST, GraphQL, STAC, OpenSearch, and CSW interfaces for discovering, searching, and ingesting metadata for satellite and Earth observation datasets spanning decades of NASA missions.
