Abstract—

A semiempirical method for studying the photochemistry of the D-region is proposed. It is based on the well-known five-component approximation (two species of positive ions, two species of negative ions, and electrons) in the stationary case. The main advantage of the method is the ability to determine the ionization rate of the ionosphere using the only parameter, the height distribution of electron density Ne(h), as experimental data on the ionosphere. The method includes a procedure for calibrating results based on solutions of forward and inverse ionospheric problems, because not all components of chemical reactions are known with sufficient accuracy. It is noted that the method can be used at different latitudes under quiet and disturbed conditions.
