Group: Summary

   Daily and monthly averaged sea ice concentrations from the Nimbus-5 
   Electrically Scanning Microwave Radiometer (ESMR) are available for the Arctic 
   and Antarctic from 12 December 1972 through 31 December 1976 at 25 km gridded 
   resolution. Raw data were reprocessed to include ocean masks that reduce 
   weather effects and coastal contamination, and to include a 15 percent ice 
   threshold. Reprocessed data are in Hierarchical Data Format (HDF) and are 
   available via FTP.
