Ionospheric electron density
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. Web7 mei 2013 · The electron density of the F2-region of the ionosphere is reflected in the values of the critical frequency foF2. During magnetic storms, the diurnal pattern of foF2is totally a quiet day pattern, depending on the nature of the interplanetary plasma conditions.
