Ionosphere heating
WebThe Total Electron Content (TEC) is the total number of electrons present along a path between a radio transmitter and receiver. Radio waves are affected by the presence of electrons. The more electrons in the path of the radio wave, the more the radio signal will be affected. For ground to satellite communication and satellite navigation, TEC ... WebThe modulation of the auroral electrojet by a ground-based ionosphere heating facility is calculated by solving a kinetic equation for electron distribution function. The resulting current is used to calculate the emission of ELF/VLF waves both into ionosphere and into the Earth-ionosphere waveguide. For this purpose, we developed a finite element …

This ionised portion of the Earth’s upper atmosphere largely owes its existence to solar ...
Web1 okt. 2024 · Abstract: Amplitude modulation high-frequency (HF) radio waves at extremely low frequencies (ELF, 0.3-3 kHz) or very low frequencies (VLF, 3-30 kHz), heating the ionosphere, can nonlinearly modulate the auroral electrojet to produce ELF/VLF waves for long-distance communication. Web6 jul. 2024 · On the theoretical side is the continuing need to understand plasma physics in general and specifically the mysteries of space weather occurring in the ionosphere where storms are constantly happening. “The ionosphere can very easily be pushed out of its equilibrium resting state,” says Hysell. “It’s much closer to the threshold of ...
Web28 nov. 2024 · We find that observed stormtime ionosphere temperature increases can be explained by the heat conduction effect. Direct heating of the ionosphere by the ring current does occur during the peak of the storm, but that occurs after the ionosphere is … Web26 okt. 2024 · We present the results of experiments on the Earth’s lower ionosphere at mesospheric heights by creating artificial periodic irregularities (APIs) of the ionospheric plasma and simultaneous measurement of the atmospheric emission spectrum in the …
