Abstract

New experimental data that confirm episodic occurrence of the correlation of light backscattering lidar signals from a height region of 150–300 km with plasma content in nighttime ionosphere F2 layer are presented. Analysis results of lidar observation data for 2008–2014 are shown. The conclusion is drawn that these correlations occur when additional sources for ionosphere ionization appear. A hypothesis that the possible mechanism for formation of these signals is the resonance scattering at excited ions of nitrogen atom is under discussion.
