Abstract

The results of monitoring of an aerosol in a near ground layer of the atmosphere of the suburb of Tomsk in this paper are discussed. The data were obtained for the years 2010-2018 at the aerosol station (V.E. Zuev Institute of atmospheric optics, Russian academy of sciences, Siberian branch) for scattering angles φ=1.2°, φ=20° with closed volume aureole photometer. The annual variations data are presented as absolute monthly average values, calculated from the hourly values of the I(φ) parameter. The analysis of the parameters of the average monthly values of the annual course revealed a certain periodicity, which was significantly affected by the natural fires of 2012. The presence of two maximums for I (1.2°), which are observed in the summer months of June-July and December and two minimums in March and November, is established. For I (20°), the maximum values are also observed in the summer months and winter in January, and the minimum in May and October.
