WebAs its name implies, the ionosphere is composed of ions, or charged particles, produced both by absorption of ultraviolet solar radiation and by the impact of the solar wind—the flow of charged particles streaming … WebApr 12, 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 network …
