Access to SnowEx, ASO, and Nimbus data sets 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 24 June 2025. The NASA Earthdata Cloud is now the primary data archive for Aquarius 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 legacy, on-premises data archive is accessed via HTTPS through https://n5eil01u.ecs.nsidc.org/.
All NSIDC DAAC data, including SnowEx, ASO, and Nimbus data sets, in NASA Earthdata Cloud can be accessed via HTTPS through https://cmr.earthdata.nasa.gov/search/site/collections/directory/NSIDC_CPRD/gov.nasa.eosdis.
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:
