NASA's Atmospheric Science Data Center (ASDC) Distributed Active Archive Center (DAAC) has scheduled system maintenance for Monday, Feb. 23, 2026, from 8 am to 5 pm ET. Data uploads, ingest and archive, processing, distribution, tools, and services may be impacted during this maintenance. We apologize for the inconvenience and will send a 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.
