Abstract

The study of the parameters of the lower ionosphere under quiet conditions and during x-ray flares of various classes remains a very topical issue to date. Diurnal, seasonal and other variations of the charged components are predicted with low accuracy, especially under the influence of various disturbances. That is why it is necessary to continue to build plasma-chemical models of the lower ionosphere and verify them using independently obtained experimental data. In this work, a comparative analysis of height profiles of Ne, NO⁺, and O₂^- concentrations obtained from four-, five-, and eight-component plasma-chemical models under quiet conditions and during x-ray flares is carried out. The best agreement with the data of ground-based radiophysical measurements in the VLF range was obtained for the eight-component scheme of the ionization-recombination cycle.
