Access to the Calibrated Enhanced-Resolution Passive Microwave Daily EASE-Grid 2.0 Brightness Temperature ESDR (NSIDC-0630), Version 2 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 11 November 2025. The NASA Earthdata Cloud is now the primary data archive for NSIDC-0630 V2 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.
All NSIDC DAAC data, including the NSIDC-0630 V2 data set, 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:
