Abstract

The results of two-frequency lidar sounding of the atmosphere from the altitudes of 25-500 km are presented. The data were obtained in 2017 at a lidar site located in Kamchatka (52°58’17”N, 158°15’07”E). The results of the sensing were recorded in the altitude area of 25-500 km. The proposed work considers the results obtained in the field of the middle atmosphere. Additional experimental data characterizing the geophysical situation that accompanied the appearance of light scattering layers in the upper atmosphere are presented. The possibility of resonance scattering in the formation of imaginary aerosol formations in the middle atmosphere is being studied. It is shown that the increased scattering at wavelengths 532 and 561 nm in the middle atmosphere region should be explained by the resonant scattering on excited ions of atomic oxygen and nitrogen. These ions may arise from the ionization of the atmosphere by relativistic electrons.
