Abstract

The results of measurements of the aerosol size distributions and number concentrations in the atmosphere of the South-Eastern coast of Lake Baikal (“Boyarsky” station) for the April, July and September 2021 are presented. Atmospheric aerosol measurements were carried out in a wide range of sizes from 5 nm to 1μm. To analyze the processes of aerosol formation and transformation, the range under consideration was divided into following mode: nucleation mode, Aitken mode and accumulation mode. The maximum concentration of the Aitken mode was prevailed in all seasons, which account for more than 63%. The highest concentrations of the nucleation mode are observed in the spring period, the share of which is 29% of the total content of the number aerosol concentration.
