Abstract
Based on measurements of brightness temperatures in the microwave range from NASA satellites using VASIA2 retrieval algorithm, the daily sea ice concentration (SIC) in the Vilkitsky Strait was reconstructed for all months of summer-autumn navigation along the Northern Sea Route for 1987-2020 period. Variations and linear trends of the monthly SIC, the probability density of the daily SIC and the variation of the SIC probability for three ranges (0-34%, 35-69% and 69-100%) of SIC reconstructed using VASIA2 and NASA Team2 (NT2) algorithms were calculated and analyzed. It was found out that VASIA2 algorithm estimates the SIC in its range of 30-100% more accurately than NT2 algorithm, and so it does it for probabilities of medium and severe (by the SIC) ice conditions at the end of the summer-autumn navigation period on the Northern Sea Route.
