NSIDC DAAC Updates Near-Real-Time SSMIS Polar Stereographic Sea Ice Concentration Data Set

The NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) has completed investigating calibration of data from the DMSP-F18 SSMIS sensor for the Near-Real-Time DMSP SSMIS Daily Polar Gridded Sea Ice Concentration data set. The tie points used with F17 SSMIS data provided the best match in sea ice extent, so no adjustment to the tie points were made for F18. The average difference between F17- and F18-derived sea ice extents were approximately 20,000 sq km. This data set now uses F17 data from 01 January 2015 through 31 March 2016 and then F18 data from 01 April 2016 onward.
