There will be a planned maintenance of database servers at NASA's Atmospheric Science Data Center (ASDC) from 5:00 to 7:00 p.m. ET on May 13, 2026. Publicly available websites and services that use these servers may experience interruptions. We apologize for any inconvenience and appreciate your patience as we work to improve our systems.
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.
