NOAAl@NSIDC is pleased to announce the release of Version 3 Revision 1 of the NOAA@NSIDC Climate Data Record of Passive Microwave Sea Ice Concentration data product. The reason for the revision change was to incorporate a new version of the input data product, Bootstrap Sea Ice Concentrations from Nimbus-7 SMMR and DMSP SSM/I-SSMIS. Another reason was to update the data that use the SSMIS instrument to also use the SSMIS pole hole mask.
