There will be a planned maintenance at the Atmospheric Science Data Center from 8am to 5pm ET on July 13, 2026. Data uploads, ingest & archive, processing, distribution, and tools & services may be impacted during this maintenance. We apologize for the inconvenience and will send notification when the work is complete.
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.
