Results of ship-based lidar studies of atmospheric aerosol fields over the water area of Lake Baikal

Abstract

The paper presents the results of lidar observations of the atmosphere over the water area of Lake Baikal. Integrated shipboard research using the research vessel «Academician V.A. Koptyug», are held annually, using the LOSA-A2 lidar, as well as local means (gas analyzers). Additionally, satellite data and information about the meteorological parameters of the atmosphere during the experiments are involved. The route of the ship goes all over the lake. An analysis is being carried out to identify the main sources of air pollution in the Baikal region.

Dependence of the concentration of small gas impurities in the air basin of the Southern Baikal region on synoptic and meteorological conditions according to the Listvyanka station

“…The ecosystems of Lake Baikal, which have been experiencing significant anthropogenic pressures for decades, have not become an exception. As previous studies have shown, the southern part of the lake, to the north-west of which industrial centers using powerful coal-fired thermal power plants as energy sources are located, is the most susceptible to the anthropogenic impact [4][5][6][7][8][9] . The main pollutants emitted during their activities are oxides of sulfur, nitrogen, carbon and suspended solids 10 .…”
