Ionosphere function
Web10 feb. 2024 · Ionosphere It is a very active layer that overlaps the mesosphere, thermosphere and exosphere, the extent of which varies depending on solar energy. The ionosphere is formed when the gases of the three layers mentioned are ionized or charged with energy, due to the effect of solar radiation. Web22 jul. 2014 · The ionosphere is divided into cells and the STEC data are gathered from ground receiver networks. The use of large and dense receiver networks observing the maximum number of GNSS satellites is necessary to obtain a better scanning of the ionosphere in terms of spatial and temporal resolutions.

WebDue to the multi-scale variability of the ionosphere and inherent biases and errors in the computation of TEC, CIT constitutes an underdetermined ill-posed inverse problem. Estimation of electron density distribution in the ionosphere as a function of space and time is a problem with important application areas.
