Based on a long series of observations of the integral coefficient of reverse aerosol scattering obtained at the Siberian Lidar Station of the IAO SB RAS in Tomsk for 2018-2025, an analysis of changes in the stratospheric aerosol layer was carried out. Trends of changes in this parameter of the atmosphere are plotted, which show a slowdown in the filling of the stratospheric aerosol. Seasonal average vertical profiles of the scattering ratio for 2023-2025 They show a decrease in values over the winter-spring period above 16 km, and summer-autumn 2023-2024, compared with the profiles of 2018-2022, slightly less or almost coincide.
