Abstract

The experimental results on the variability of the vertical-temporal structure of the stratospheric aerosol over Tomsk, obtained at the lidar complex of the Small Lidar Station of IAO of the SB RAS in the period 2011-2015 are presented. The characteristic peculiarity of this period, except of the second half of 2011, (appearance of the eruptive layers of the Grimsvotn volcano eruption over Tomsk) was practical absence of volcanic activity leading to the formation of stratospheric aerosol and its transfer to Tomsk, and therefore it became possible to study the behavior of the vertical structure of the background aerosol in the stratosphere during five years. According to the analysis of the lidar data obtained, a stable trend of aerosol filling of the lower stratosphere during the cold season with its maximum content in December-January and a practical absence of aerosol in the entire stratosphere layer during the warm season was revealed.
