To be submitted to JGR-Oceans Studies of Antarctic Sea Ice Concentrations from Satellite Data and their Applications
Large changes in the sea ice cover have been observed recently. Because of the relevance of such changes to climate change studies it is important that key ice concentration data sets used for evaluating such changes are interpreted properly. High and medium resolution visible and infrared satellite...
