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%. The average aerosol characteristics for the entire Kara Sea are: the atmospheric AOD (0.5 μm) is 0.043 with an Ångström exponent of 0.8, еВС = 22.8 ng/m3, Vf = 0.26 μm3/cm3, and Vс = 1.39 μm3/cm3. The average Vf and еВС over the Kara Sea are shown to be intermediate between the values for the Cape Baranov and the Barents Sea.
期刊介绍：
Atmospheric and Oceanic Optics is an international peer reviewed journal that presents experimental and theoretical articles relevant to a wide range of problems of atmospheric and oceanic optics, ecology, and climate. The journal coverage includes: scattering and transfer of optical waves, spectroscopy of atmospheric gases, turbulent and nonlinear optical phenomena, adaptive optics, remote (ground-based, airborne, and spaceborne) sensing of the atmosphere and the surface, methods for solving of inverse problems, new equipment for optical investigations, development of computer programs and databases for optical studies. Thematic issues are devoted to the studies of atmospheric ozone, adaptive, nonlinear, and coherent optics, regional climate and environmental monitoring, and other subjects.
