The NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) has updated the Near-Real-Time DMSP SSMIS Daily Polar Gridded Brightness Temperatures data set so that it now solely provides data from the DMSP-F18 SSMIS sensor beginning with 01 April 2016 due to the compromised data integrity of the DMSP-F17 SSMIS vertically polarized 37 GHz channel (37V). Data before 01 April 2016 are still from the F17 SSMIS.
