Analysis of the empirical median ionosphere model constructed using IRI local passive radiosonding data

The article describes one of the ways to establish radio communication on short waves, which is actively used in practice. When establishing such a connection, it is necessary to take into account the parameters of the ionosphere, which is subject to various external influences. Therefore, in order to establish a reliable communication channel of this kind, it is necessary to use models predicting the parameters of the ionosphere. The author of the article describes the methods of constructing such models and analyzes one of the most frequently used models of the ionosphere, which is based on passive radiosonding data. Using methods of statistical data processing, ways to improve the parameters of such an ionosphere model are proposed.
