Abstract

In the period from 2010 to 2021, in the village of Boyarsky on the eastern coast of Baikal Lake, studies were carried out on the vertical structure of aerosol fields in the troposphere. The measurements were carried out using the LOSA-M2 aerosol-Raman lidar in the summer (July - August). A total of 93 cycles of daily observations were carried out during this period. The report presents typical patterns of transformation of aerosol layers under various synoptic conditions. Particular attention is paid in the report to the relationship between the structure of the boundary layer and the direction of movement of air masses. With a southeasterly wind prevailing at the observation site and directed along the coast, a characteristic diurnal dynamics of the boundary layer is observed with the development of a mixing layer during daytime heating of the surface. When air masses formed above the cold surface of the lake are brought in, a layered structure without pronounced updrafts prevails.
