The structure and dynamics of the HF-pumped ionosphere based on a joint analysis of the artificial airglow spots and two-dimensional maps of the total electron content

Abstract

© 2019 IEEE. The paper carries out preliminary processing of experimental data for August 29, 2016, obtained during joint measurements of artificial variations in the total electron content of the ionosphere on a network of 20 GNSS stations located within a radius of 400km from the 'Sura' facility, mainly in eastern and southeastern directions, and artificial airglow in the 630nm red line of atomic oxygen, stimulated by powerful radio emission from the 'Sura' facility. A direct comparison between the images of artificial airglow spots and TEC maps is presented. Dynamic spatial-temporal picture of the TEC variations in the heating region of the HF-pumped ionosphere, where plasma waves are generated, capable of accelerating electrons to the excitation potential of optical levels is obtained.
