Abstract
Abstract An algorithm is developed and tested for assessing the types and concentrations of sea ice on the basis of data obtained from two‐band active and passive microwave sensors, using a priori values of the scattering parameters and natural emission of basic types of ice for the corresponding characteristics of the observation system—frequency, polarization, and observation angle—and a linear mixture model for the measured radiobrightness temperature and specific effective scattering area. The results of satellite monitoring with a side‐looking radar with a real SLR aperture and an RM‐08 microwave radiometer, of the region of the Barents‐Kara‐Laptev seas and the adjacent Arctic Ocean, were used in organizing a satellite database for the period October 1995–March 1996, in compiling digital mosaic charts of the ice cover, and in making a comparative analysis with the corresponding charts prepared by the U.S. Navy and National Oceanic and Atmospheric Administration.
