Abstract

Lake Baikal is a unique natural object. Study of the composition and optical characteristics of aerosols in the atmosphere above it is an urgent problem. This work analyzes the results of studies of the microstructural and physicochemical properties of near-water and near-ground aerosol in the atmosphere of Lake Baikal basin in summer 2024 onboard Research Vessel Akademik V.A. Koptyug and at the Boyarsky research station on the southeastern coast of the lake. The aerosol spatial distribution over the lake water area and the content of black carbon in aerosol particles are shown to be determined by the location of anthropogenic sources in the absence of smoke plumes from wildfires. Hygroscopicity and volatility of atmospheric aerosols, which depend on aerosol particle size, are studied for the first time. The aerosol condensation activity over the coastal zone is found to be stronger than over the lake. The results can be useful for the development of regional models of atmospheric aerosol.

2024年夏季贝加尔湖及南岸地区大气气溶胶微观结构及吸湿吸收特性

贝加尔湖是一个独特的自然景观。研究其上空大气中气溶胶的组成和光学特性是一个迫切需要解决的问题。本文分析了2024年夏季贝加尔湖盆地大气中近水和近地气溶胶的微观结构和物理化学性质的研究结果，这些研究结果是在科普丘格院士号科考船和位于湖东南海岸的博雅尔斯基研究站上进行的。湖泊水域上空的气溶胶空间分布和气溶胶颗粒中黑碳的含量表明，在没有野火产生的烟柱的情况下，由人为源的位置决定。本文首次研究了大气气溶胶的吸湿性和挥发性与气溶胶粒径的关系。沿海地区的气溶胶凝结活动强于湖泊上空。研究结果可为区域大气气溶胶模式的发展提供参考。

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.
