WebGeophysically, the state of the ionospheric plasma may be described by four parameters: electron density, electron and ion temperature and, since several species of ions are present, ionic composition. Radio propagation depends uniquely on electron density. Models are usually expressed as computer programs. Web28 mei 2024 · NeQuick is a semi-empirical climatological model that describes spatial and temporal variations of the ionospheric electron density at any location by using the peaks of the three main ionospheric regions (E, F1, and F2) as anchor points. STEC can be computed by integrating along the electron density path in each direction.
