Sea Ice Concentration

Sample images of NOAA CDR Sea Ice Concentration product. It depicts the percent of concentrated sea ice over the norther hemisphere in a three image series, September 5th 1987, September 23rd 1997, and September 16 2007, indicating a marked decrease over time.

This dataset provides a high quality Climate Data Record (CDR) of Sea Ice Concentration.

The Sea Ice Concentration CDR provides a consistent, daily and monthly, time series of sea ice concentrations for both the north and south Polar Regions on a 25 km x 25 km grid. These data comprise an estimate of the fraction of ocean area covered by sea ice that is produced by combining concentration estimates created using two algorithms developed at the NASA Goddard Space Flight Center (GSFC). Gridded brightness temperatures acquired from a number of Defense Meteorological Satellite Program (DMSP) passive microwave radiometers provide the necessary input to produce the CDR.
