摘要：
In this study we have verified the algorithms for the Arctic sea ice concentration (SIC) retrieval from the data of the Russian satellite microwave imager/sounder MTVZA-GYa. The algorithms are based on the polarization differences (PD), measured by the MTVZA-GYa at the frequencies of 10.6 and 36.7 GHz. Verification is done with the SIC satellite product based on the data of the Advanced Microwave Scanning Radiometer 2 (AMSR2) produced with an advanced algorithm from PD measurements at 89 GHz. Verification is done using collocated in time and space AMSR2 and MTVZA-GYa measurements taken in 2020. Analysis of additional high resolution Sentinel-1 Synthetic Aperture Radar (SAR) data have shown that the usage of low frequency MTVZA-GYa PD measurements allow avoiding underestimation of SIC for some areas featured to high frequency AMSR2 PD measurements.
