Access to the Near-Real-Time AMSR2 EASE-Grid Daily Global Ice Concentration and Snow Extent, Version 1 data set in the legacy, on-premises archive at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) will be retired on 28 October 2025. The NASA Earthdata Cloud is now the primary data archive for the data. If you currently access data through the legacy, on-premises archive, including through the HTTPS File System or through the Earthdata Search Stage for Delivery (ECHO Orders) option, please update your data access workflows and scripts to use the Earthdata Cloud archive.
The NASA Earthdata Cloud NISE_A2 archive is accessed via HTTPS through https://nsidc.org/data/nise_a2/versions/1
The NSIDC DAAC User Services Office provides support for direct data download from Earthdata Cloud HTTPS and access to our AWS Simple Storage Service (S3) buckets. For more details on these access options, please see: https://nsidc.org/data/user-resources/help-center/nasa-earthdata-cloud-data-access-guide
