Paper 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). One lidar channel is applied to investigate the aerosol formations in the middle atmosphere and to record the resonance scattering on excited ions of atomic nitrogen in the upper atmosphere. Nd:YAG laser operating on the wavelength of 532 nm is used in this channel. A dye laser with tunable frequency is applied in the second channel. The wavelength of 561.1 nm corresponds to the chosen dipole transition between the excited states of atomic oxygen. This paper discusses the results of probing in the middle atmosphere in the region of 25-80 km, obtained on 5.09.2017. It is shown that during lidar probing of the middle atmosphere imaginary aerosol formations can be observed, caused by precipitations of charged particles
