Resonant Scattering by Excited Gaseous Components as an Indicator of Ionization Processes in the Atmosphere

The results of lidar sensing the atmosphere at altitudes in range 25–600 km from Kamchatka Lidar Station (53° N, 158° E) obtained 2008–2022 are presented. an analysis data two-frequency thermosphere given. increased scattering wavelengths 532 and 561 nm is due to resonant by excited atomic nitrogen oxygen ions. Manifestations middle also discussed. It demonstrated that these ions during process ionization main atmospheric species precipitation energetic electrons. findings show that, soundings atmosphere, can form imaginary aerosol formations. spectrum precipitating electrons be estimated shape position maximum signal profile. shown excitation ground state does not play any significant role formation backscattered signal. carry information about content height profile state. appearance indicates presence sources.
