NASA's Atmospheric Science Data Center (ASDC) has maintenance activities scheduled from 9:00 a.m. to 5:00 p.m. EDT on May 29, 2026. Some data processing, receiving, ingesting, and archiving systems will be temporarily unavailable during the maintenance. This outage disables Direct Data Download and website-related URLs (access to documents), along with MISR order tool and the MISR L3 web tool.
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.
