Sea Ice Concentration CDR Updated to Version 3 Revision 1

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. In previous versions, the larger SSM/I pole hole mask was being used for these data, which was cutting out a section of valid data. In addition, this fixes a bug in the code that was causing some sections of the time series to not produce output files. Further, the data now go through 28 February 2017. To access these data, visit the data set landing page for the NOAA@NSIDC Climate Data Record of Passive Microwave Sea Ice Concentration, Version 3.
