Abstract
The results of the analysis of seasonal and interannual variability of the aerosol optical depth of the atmosphere (AOD), the aerosol volume concentration, and the mass concentration of black carbon in the surface layer obtained at observations in Barentsburg (Spitzbergen archipelago) in 2011–2021 are presented. The annual behavior of all parameters is characterized by two maxima: spring (or winter-spring) and summer, apparently due to the transport of pollutants from the middle latitudes in the winter-spring period and smoke aerosol in summer. In the interannual variability, there are significant negative trends in the fine AOD component (−0.012 over 11 years) and the mass concentration of the absorbing substance (by 46.7 ng/m3 over 10 years).
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.
