Abstract

The data of annual variability of the aerosol vertical-temporal structure and total content in the stratosphere, obtained at the lidar complex of the Siberian Lidar Station of the IOA SB RAS in 2016 - 2019. A data array of 357 total signals detected in individual nights of these years was used as the initial information for analysis. The range of the heights of sounding was from 10 to 50-60 km, the spatial resolution was 192 m, the accumulation time of the total signal was 2 hours. According to the results of observations, as in previous years, a steady increase trend in the accumulation of stratospheric aerosol was observed from the middle of the year with a maximum content in January and a decrease to a practical absence in June-July. The background aerosol is absent in the upper stratosphere (30–50 km) throughout the year.
