Near-Real-Time DMSP SSMIS Daily Polar Gridded Sea Ice Concentrations, Version 1
Due to technical difficulties, there is a delay in the release of the most recent data for this product. We are working to make the data available as soon as possible. Please contact NSIDC User Services if you have any questions.
Notice (04/21/2016): On 04/05/2016 a change in the solar panel position to shade the nitrogen tank on board the Defense Meteorological Satellite Program (DMSP) F-17 satellite was made. In doing so, the integrity of the vertically polarized 37 GHz channel (37V) of the Special Sensor Microwave Imager and Sounder (SSMIS) was compromised. On 04/13/16 an additional change in the solar panel position was made. This change had improved the problems we were seeing in the 37V GHz channel for data from April 13 to April 19; however, on April 20, the 37V GHz channel started to produce bad data again. Thus, data from April 20 onward should not be used until further notice. The affected daily files from 04/05 - 04/13 have been removed from distribution.
This data set provides a Near-Real-Time (NRT) map of sea ice concentrations for both the Northern and Southern Hemispheres.
