The results of lidar and ionospheric observations from August to November 2017 are discussed. Resonance scattering was detected at wavelengths of 532.08 and 561.106 nm in the altitude range of 200-400 km and in the middle atmosphere. A possible mechanism for the formation of a resonant scattering signal on excited ions of the main gas components of the atmosphere is presented. The possibility of estimating the spectra of precipitated electrons is shown.
It is shown that the complete profile of the backscattering signal can be restored in the region of 10–25 km using an additional channel for recording the attenuated signal separated from the main signal. Thus, it becomes possible to estimate the energies of electron flows in the entire region from the lower thermosphere to the stratosphere.
