Abstract

The results are presented of the study of planetary boundary layer of the atmosphere in the Western Siberian region, as well as retrieval of its optical and geometric characteristics from the data of lidar measurements. The basis of the study are 110 seances of sounding by means of the LOSA-S multi-frequency lidar in Tomsk (56°N, 85°E). Measurements of the optical characteristics in the boundary layer caused by transfer of aerosol from different geographic regions are considered. High values of the lidar ratio (66 sr) and the Angstrom exponent (1.62) are observed in the short-wave range in he boundary layer at transfer from Arctic. At the same time, low values of these parameters are characteristic of the transfer from Asia: lidar ratio 54 sr, Angstrom exponent 1.1, that is explained by different ratio of coarse and fine aerosol fractions in an air mass.
