Abstract: | A relatively simple steady-state ion-chemical model for the non-auroral D- and lower E-regions is presented. Solar fluxes and the neutral atmospheric constituents are taken from up-to-date literature. The model results are systematically compared to measurements, namely: ion composition, electron density vs solar zenith angle, solar activity, season and latitude. Although the agreement is not always good, it is believed to exceed that of purely statistical models. |
