Documentation    Access Data    

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.
