The following data sets will be retired from NSIDC on July 31:
- NOAA/NSIDC Climate Data Record of Passive Microwave Sea Ice Concentration, Version 4
- Near-Real-Time NOAA/NSIDC Climate Data Record of Passive Microwave Sea Ice Concentration, Version 2
After retirement, these data sets will no longer be accessible, though all documentation will remain available on the data set web pages for reference. We recommend using the latest versions: NOAA/NSIDC Climate Data Record of Passive Microwave Sea Ice Concentration, Version 5 and NOAA/NSIDC V5 and Near-Real-Time NOAA/NSIDC Climate Data Record of Passive Microwave Sea Ice Concentration, Version 3. These can be accessed through the "more recent version" link on each web page. The latest versions of the NOAA/NSIDC sea ice concentration climate data record will continue to be maintained.
