Short summary
The Electrically Scanning Microwave Radiometer, the first spaceborne microwave instrument to map global sea ice, was launched aboard the NIMBUS 5 satellite in December 1972 and remained operational until May 1977. As part of the European Space Agency's Climate Change Initiative, this dataset has been reprocessed and validated to provide a nearly complete global record of sea ice concentration, with only a few data gaps in 1973 and 1975.
