Improved aerosol scattering in the upper atmosphere, according to data of ultraviolet observations from space, with instrumental smoothing taken into account

According to data of space observations, the aerosol scattering parameters in the Earth's upper atmosphere obtained by the method of tangent sensing in ultraviolet wavelength range (273, 280 nm) with the help of the astrophysical space station Astron are presented. The inverse problem of remote sensing was solved taking into account vertical smoothing effects for altitude dependence of the atmospheric spectral brightness observed in the Earth's limb. High turbidity is observed under unperturbed atmospheric conditions at altitudes near 50 km and between 65 and 100 km. Splitting of aerosol layers at altitudes near 80 and 93 km when instrumental smoothing effect is taken into account is rather obvious. It is established that after Space Shuttle launches a long-lived and extended aerosol layer is formed along the active trajectory of launch at altitudes near 100 km. The characteristic transverse size of anthropogenic layer zone is about 900 km, though the perturbation is observed up to 1500 km.
