Web2 mei 2024 · where Re is the Earth radius, θ is the LOS elevation angle and Hion is the altitude of ionospheric detection. The Hion cannot be known because the sTEC is an integral parameter. Based on the physical principles, the Hion is presumed to be around the ionization maximum, that is around 250–350 km. Here we take Hion = 250 km for all events. Web24 jan. 2024 · The large amount of data that are available for ionospheric studies using the GPS TEC method, as well as the need to take into account complex atmospheric dynamics, create certain difficulties in automating the process of searching and recognizing traveling ionospheric disturbances generated by different sources. To automate the process of …
