Sea Ice Index

Description

Sea Ice Index products offer information about ice cover and its trends in the Arctic and Antarctica. In this collection, sea ice extent and concentration maps are provided at a resolution of 25 km on a daily basis. The products are computed using images from the Special Sensor Microwave Imager (SSM/I) and Special Sensor Microwave Imager/Sounder (SSMIS) instruments on Defense Meteorological Satellite Program (DMSP) satellites. Sea ice concentrations are generated from brightness temperature data. Sea ice extent is computed as areas covered by ice with a concentration greater than 15 percent. This dataset is for demonstration purposes only and is not maintained.
