Theory of ionospheric waves
Webbacoustic gravity waves generated in the earthquake zone on the ionosphere, and the second was anomalous vertical electric fields penetrating from the earthquake zone into the ionosphere. We can consider conductivity changes in the air as an option in the electric field model. Initially, the acoustic hypothesis led studies in this area. Webb12 apr. 2024 · Ionospheric effective height (IEH), a key factor affecting ionospheric modeling accuracies by dominating mapping errors, is defined as the single-layer height. From previous studies, the fixed IEH model for a global or local area is unreasonable with respect to the dynamic ionosphere. We present a flexible IEH solution based on neural …
