Access to ICESat-2 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 July 15, 2025. The NASA Earthdata Cloud is now the primary data archive for ICESat-2 data. Transformation services are available for select data sets through NASA Earthdata Harmony. 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. If you use the icepyx tool, please update your tool to version 2.0.0 to avoid errors when ordering data: https://icepyx.readthedocs.io/en/latest/index.html
We expect Version 7 data sets to become available this summer, and this version will only be available from the Earthdata Cloud archive. Earthdata Harmony transformation services will be available within the coming months following this release. Available services are listed at:
