Web17 mei 1990 · This invention relates to generation of a Artificial Ionospheric Mirror (AIM), or a plasma layer in the atmosphere. The AIM is used like the ionosphere to reflect RF energy over great distances. A tiltable AIM is created by a heater antenna controlled in phase and frequency. The heater antenna phase shift scans a beam to paint a plasma layer. WebIonospheric heater beam scanning: A mobile source of ELF radiation Semantic Scholar. The heating facility at Ramfjordmoen near Tromso, Norway, is used to modulate the …

An ionospheric heater, or an ionospheric HF pump facility, is a powerful radio wave transmitter with an array of antennas which is used for research of plasma turbulence, the ionosphere and upper atmosphere. These transmitters operate in the high frequency (HF) range (3-30 MHz) at which radio … Meer weergeven • EISCAT-Heating operated by the European Incoherent Scatter Scientific Association (EISCAT) at Ramfjordmoen near Tromsø in Norway, capable of transmitting 1.2 MW or over 1 GW [1] [2] effective radiated power Meer weergeven • Arecibo Observatory also had a HF facility for ionospheric modification.

Web4 aug. 2024 · What follows is Ozone destruction and generation of N O x -species in the Mesosphere and Stratosphere. N O x molecules are classical long-lived Ozone killers. The Ozone depletion leads to direct heating of the Polar surface of up to Δ T ≈ 4.5 K by increased UV irradiation. WebIonospheric F-region heating by a high-frequency transmitter (100 kW at 5.62 MHz fed into a 1000-ft dish producing a beam with an angular half-width of 10 deg) was observed with a 430-MHz incoherent scatter radar, an ionosonde, and several photometers. The electron temperature of the ionosphere was increased by as much as 30% at and just below the … WebThe Russian Woodpecker, Chernobyl Meltdown, and Ionospheric Heating Over the USA (1983-1986) 1983-1986.
