The Sea Ice Concentration Climate Data Record (CDR) is a set of consistent, daily and monthly sea ice concentration data time series. Data is available for both the north and south Polar Regions on a 25 km x 25 km grid from 1978–present. These data can be used to estimate how much of the ocean surface is covered by ice and monitor changes in sea ice concentration.

This CDR combines concentration estimates using two algorithms developed at the NASA Goddard Space Flight Center (GSFC). Gridded brightness temperature data inputs come from the following sources:

Nimbus-7 Scanning Multichannel Microwave Radiometer (SMMR) Defense Meteorological Satellite Program (DMSP) series of passive microwave radiometers Special Sensor Microwave Imager (SSM/I) Special Sensor Microwave Imager/Sounder (SSMIS)},
