The National Snow and Ice Data Center has learned that NASA will discontinue processing of the AMSR Unified suite of data sets. One of the products in this suite is used as input for the prototype AMSR2 sea ice concentrations in the sea ice CDR data set. As a result, the NOAA/NSIDC sea ice concentration NRT CDR Version 3 data set will no longer contain the AMSR2 prototype data after 1 September 2025. It will continue to have the SSMIS-derived sea ice concentrations. NSIDC is working to release a new version of the sea ice CDR that will include AMSR2 from a different data provider.
