Near-Real-Time DMSP SSMIS Daily Polar Gridded Sea Ice Concentrations, Version 1

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), which is a primary channel used for sea ice development, NSIDC is halting production of the Near-Real-Time DMSP SSMIS Daily Polar Gridded Sea Ice Concentrations F17 data and switching over to the F18 satellite, starting with 1 April 2016 data. However, NSIDC is still working on the calibration of the F18 data so temporarily the F18 data will be uncalibrated and using F17 tie points.

This data set provides a Near-Real-Time (NRT) map of sea ice concentrations for both the Northern and Southern Hemispheres.
