Due to the compromised data integrity with the Defense Meteorological Satellite Program (DMSP) F-17 vertically polarized 37 GHz channel (37V) of the Special Sensor Microwave Imager and Sounder (SSMIS), NSIDC will be distributing data from both the F17 and F18 satellites, starting with 1 April 2016 data. Using data from the 37V channel from the F17 satellite is not recommended. Instead, you should use data from the F18 satellite’s 37V channel.
