Abstract
The paper presents the results of investigation of temporary changes in the vertical structure of aerosol fields in the mountain valley of Lake Baikal, in the presence of sources of smoke, from both remote and local forest fires. Measurements were carried out using the LOSA-M2 lidar, located on the east coast of Lake Baikal, during the expeditions of 2013 and 2015, when extremely high values of aerosol content in the troposphere caused by forest fires were observed. There is a significant difference between the space-time structures of the smoke aerosol from local forest fires in the basin of the lake, from the case when the impurity sources are located at a considerable distance.
