This product relies on the high resolution SSM/I brightness temperatures (85 GHz channels) with the low resolution data as background.
The sea ice concentration product is generated daily from the brightness temperature maps provided by the National Snow and Ice Data Center (NSIDC, Boulder, Colorado) , using the ASI algorithm (Bremen University). The Arctic sea ice concentration time series starts on December 1991 and is on going. Monthly averages are also available.
The geographic coverage, the projection and the pixel size are identical/compatible to/with those of the NSIDC SSM/I data and with the scatterometer backscatter maps/ the drift fields produced by IFREMER.
