Abstract

In this paper Special Sensor Microwave Imager (SSM/1) and Advanced Very High Resolution Radiometer (AVHRR) sea ice mapping capabilities are analysed using Antarctic data acquired during November 1990 over the Ross Sea. Quantitative comparisons between sea ice concentrations obtained from SSM/1 and AVHRR data show differences of -10% to +50% with average differences between 9% and 17%. These differences are mainly attributed to: sea ice reflectance and emissivity spatial variations occurring during the melting season, which reduce the accuracy of concentrations obtained with global tie points; and colocation inaccuracy between SSM/1 and AVHRR grids.
