Optical Aerosol Model of the Western Siberian Stratosphere Based on Lidar Monitoring Results

Abstract

The long-term series of observations of the vertical stratification of aerosol in the stratosphere are processed and analyzed using the scattering ratio as an example, as well as the vertical distribution of aerosol scattering coefficients at a wavelength of 532 nm (altitude range 15–50 km) over Tomsk. The experimental data were received from regular measurements at the lidar station of V.E. Zuev Institute of Atmospheric Optics, Siberian Branch, Russian Academy of Sciences, in 2010–2021. On the basis of the accumulated experimental material, regional features of the intra- and interannual variability of the stratospheric aerosol are ascertained for Western Siberia. An optical aerosol model of the atmosphere is suggested which better corresponds to this region than existing models.
