Abstract:

The Special Sensor MicrowaveImager SSMI, which is part of the Defense Meteorological Satellite Program DMSP, is a coarse resolution passive microwave sensor with good aerial coverage of the Arctic region. Since the SSMI sensor produces nearly full coverage of the Arctic region each day, data generated by this sensor is used to obtain geophysical parameters associated with the Arctic area. An algorithm has been developed at Goddard Space Flight Center which produces both multiyear and total ice concentration estimates from SSMI data. This paper presents comparisons between these SSMI derived ice concentration estimates and estimates derived from high resolution SAR data that was collected co-incident to the SSMI overpass. Data from the Beaufort and Bering Seas collected in March of 1988 is used and both the multilayer concentration algorithm and the total ice concentration algorithm are compared. A discrepancy between the two estimates is analyzed and a possible explanation based on the scattering from ridging in first-year ice is presented.
