Paper Abstract

Satellite passive microwave sensors are the most effective means to monitor sea ice on a global scale. 18 GHz horizontal and vertical and 37 GHz vertical polarized brightness temperatures from the Scanning Multichannel Microwave Radiometer (SMMR) are compared to the 19 GHz horizontal and vertical and 37 GHz vertical polarized brightness temperatures from the Special Sensor Microwave Imager (SSMI) over the Arctic and Antarctic during the 1987 overlap period n order to merge the two time series. The Norwegian NORSEX and NASA Team multi-frequency algorithms are used on the overlapping SMMR and SSMI data sets. Sea ice extent and area are calculated and the algorithm performance is compared for both hemispheres. The NORSEX algorithm tends to give approximately 10% higher sea ice concentration values than the NASA Team algorithm.
