Web29 sep. 2006 · The Fast Langmuir Probe (FLP) was installed on the sounding rocket to study thermal structure and energy balance of the plasma by measuring the electron temperature in the polar lower ionosphere. The FLP observations indicate that the electron temperatures were found to be remarkably high in an altitude range from 106 km to 114 km during the … WebIonospheric heating by powerful radio waves. Abstract: In addition to the communication applications that stem from the generation of field-aligned irregularities, ionospheric heating by powerful HF waves also holds promise for establishing new techniques in D-, …

First, it is found that the observed ionospheric response … Web2 dec. 2024 · The data on joint processing of the values of the equivalent polar electrojet current above the heated ionosphere region retrieved by the IMAGE network of ground-based stations and the amplitudes of a signal of the horizontal component of the magnetic field from an ionospheric source at the modulation frequency recorded in the PGI …
Web27 okt. 2024 · The Earth’s ionosphere is a natural layer of charged particles at approximately 80-1,000km altitude. This ionised portion of the Earth’s upper atmosphere largely owes its existence to solar ... 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 …
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 ...
Webby modulated heating of the ionosphere has been the subject matter of numerous papers [7-13]. In 1974, it was shown that ionospheric heater can generate ELF waves by heating the ionosphere with high-frequency (HF) radiation in the megahertz range [7].
