Spatial Distribution and Average Characteristics of Atmospheric Aerosol in the Kara Sea Basin

Based on long-term study in the Kara Sea basin (11 expeditions in 2007–2022), we, for the first time, statistically generalize atmospheric aerosol characteristics: the volume concentrations of submicron and coarse aerosol (Vf and Vс), the black carbon concentrations (еВС), and the spectral aerosol optical depth (AOD) of the atmosphere. High concentrations of submicron and absorbing (eBC) aerosol are pronounced in the average spatial distribution in the southwestern part of the Kara Sea, and they are minimal in the northern part. The difference in the average Vf and еВС between these regions is 30–60
