- Аннотация: The results of scientific experiment, conducted in the Meteorological Observatory of Moscow State University in July-August of 1998, are presented. At that time the vertical sodar ‘ECHO-1’ and the aerosol lidar were in work simultaneously within 18 days. The purpose of the experiment was to study particularities of aerosol concentrations and their connections with synoptic processes and a thermal stratification, derived indirectly by the sodar data. The results demonstrate an evening increasing of aerosol concentrations in the ground layer due to decay of convective vertical mixing. Vice versa, in the morning aerosol concentrations usually tend to decrease sharply after vanishing of a nocturnal inversion’s layer. When an elevated inversion exists its bottom by the sodar data can be connected with a top of a high-concentrated aerosol layer beneath. Besides, dynamics of aerosol concentrations from day to day can be successfully explained by synoptic processes, because it seems to clearly depend on a type of air mass, dominating above Moscow.
