Sea Ice Climate Normals (1981-2010) of Arctic and Sub-Regions, Version 1

The 1981-2010 Sea Ice Climate Normals are the latest three-decade average of Arctic sea ice concentration, area, and extent computed from monthly satellite sea ice concentration estimates from a climate data record (CDR) produced by NOAA and the National Snow and Ice Data Center (NSIDC). The data file formats are NetCDF for the sea ice concentration normals, and ASCII text for the sea ice area and sea ice extent normals.
