• NSIDC DAAC is currently upgrading our data ingest process for NASA Earthdata Cloud. During this transition, users may notice temporary interruptions in data availability or notice small data gaps. All gaps will be resolved as quickly as possible. During this upgrade jpeg browse imagery will also not be available for preview in Earthdata search. Please reach out to NSIDC User Services with any questions or concerns.

  • On Wednesday, September 24 from 9:00 a.m. to 1:30 p.m. (US Mountain Time), this data set may not be available in the legacy data archive due to a planned system maintenance. Earthdata Cloud access will remain available for data sets that have migrated. Users of the SMAP near real-time products should use the NASA LANCE HTTPS File System for data access.

  • The NSIDC DAAC is retiring access to its legacy, on-premises data archive and transitioning to the NASA Earthdata Cloud as the primary data archive. View planned retirement dates here.
