The mechanisms of solar electromagnetic and corpuscular radiation influence upon ionospheric state at different altitudes were investigated. Comparative analysis of different types of wave ionosphere perturbations was done. Main signatures of Sun-made perturbations responsible for space weather formation were determined. Criteria for selection of ionosphere perturbations caused by solar activity from different types of ionosphere perturbations were elaborated. Particularly, the regular ionospheric perturbations caused by solar terminator and sporadic ionosphere variations caused by meteorological and seismic activity was studied. Technique for determination of plasma wave spectrum composition was elaborated. Product Description popup.authors popup.nrat_date 2020-04-02 Close
