There will be a planned maintenance at NASA's Atmospheric Science Data Center from 8 a.m. to 5 p.m. ET on May 26, 2026. Data uploads, ingest and archive, processing, distribution, and tools and services may be impacted during this maintenance. We apologize for the inconvenience.
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.
