Ionospheric variations
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. WebOne of the methods of detection and analysis of solar flares is observing the time variations of certain solar spectral lines. During solar flares, a raise of electron concentration occurs in Earth's ionosphere which results in amplitude and phase variations of the recorded very low frequency (VLF) waves. We compared the data obtained by the analysis of recorded …
