摘要

An analysis of the Kamchatka lidar station data obtained in January-February 2021 is presented. We have confirmed the main conclusions of works on the causes and mechanism of formation, as well as the main properties of the backscattering profile in the presence of additional sources of atmospheric ionization. It is shown that the observed aerosol formations in the mesopause region could be caused by precipitation of charged particles with energies less than 500 eV, which is confirmed by the simultaneous growth of the ionospheric parameter fmin. Aerosol formations in the area of 60 - 75 km should be recognized as imaginary. They are caused by resonant scattering by excited ions of atomic nitrogen and oxygen. The possibility of estimating the energy of precipitated electrons is shown.
