There will be scheduled maintenance at NASA's Atmospheric Science Data Center (ASDC) from 7 a.m. to Noon ET on June 4, 2026. Expect some disruptions to data uploads, processing, and services. We will notify you when services are restored.
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.
