Access to SMAP 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 28 October 2025. The NASA Earthdata Cloud is now the primary data archive for SMAP data. If you currently access data through the legacy, on-premises archive, including through the HTTPS File System, Earthdata Search Stage for Delivery (ECHO Orders), or Customize (ESI) in Earthdata Search or the EGI API, please update your data access workflows and scripts to use the Earthdata Cloud archive. Transformation services through the Customize (ESI) option in Earthdata Search and the EGI API will be retired, with replacement services coming on 15 October 2025.
All NSIDC DAAC data, including SMAP 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:
