On May 6 from 8:00 to 9:00 a.m. (US Eastern Time), the Data Catalog and Earthdata Search search may be temporarily unavailable due to maintenance of the NASA Common Metadata Repository (CMR).

We are in the process of migrating all NASA Earth science data sites into Earthdata from now until end of 2026. Not all NASA Earth science data and resources will appear here until then. Thank you for your patience as we make this transition. Read about the Web Unification Project
