Notice (05/05/2016): Due to the compromised data integrity with the DMSP F17 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.
The Near-Real-Time DMSP SSM/I-SSMIS Daily Polar Gridded Brightness Temperature product provides near-real-time brightness temperatures for both the Northern and Southern Hemispheres. These brightness temperatures are used to generate the Near-Real-Time DMSP SSM/I-SSMIS Daily Polar Gridded Sea Ice Concentrations.
