Abstract
The results of two-frequency lidar sensing of the atmosphere at the lidar station of Kamchatka (52°58¢17¢¢ N, 158°15¢07¢¢ E) are discussed. The results of sounding were registered in the altitude range 25-600 km. The results obtained in the middle atmosphere are considered. The possibility of resonance scattering in imaginary aerosol formations in the middle atmosphere is studied. Examples are given in which the increased scattering at wavelengths of 532.08 and 561.106 nm in the middle atmosphere should be explained by the resonance scattering on excited ions of atomic oxygen and nitrogen. These ions may appear as a result of the ionization of the atmosphere by relativistic electrons.
