Penetration of lightning MF signals to the upper ionosphere over VLF ground-based transmitters
[1] The MF data recorded by the low-altitude satellite DEMETER have been used to survey the MF waves around the Earth. A global map of the MF emissions indicates that there exists a wave activity in the frequency range 2–2.5 MHz above the main powerful VLF ground-based transmitters operating in the frequency range 18–50 kHz. It is shown that this is due to the high-frequency part of whistlers i...
متن کاملVLF, magnetic bay, and Pi2 substorm signatures at auroral and midlatitude ground stations
[1] A superposed epoch analysis of 100–300 substorms is performed to determine the median size and shape of the substorm-associated VLF chorus, magnetic bay, and Pi2 pulsation burst observed at the near-auroral Halley research station, Antarctica, and at the midlatitude Faraday station at three different local times (2230, 2330, 0130 MLT). The spatial and temporal properties of the magnetic bay...
متن کاملElectron precipitation coincident with ELF/VLF wave bursts
[1] On 15 October 1999, charged particle and plasma wave detectors on the Polar satellite observed an enhancement in precipitating energetic electrons coincident with an ELF/VLF electromagnetic emission. Assuming that the electromagnetic wave was field aligned and scattered trapped electrons by first-order cyclotron resonance near the equatorial plane, the resulting pitch angle distribution of ...
متن کاملGround-based remote sensing of precipitation in the Arctic
[1] In this paper, a simple technique is described for application of radar to retrievals of vertical profiles of precipitation in the Arctic. The method is applied specifically to data from the DOE Atmospheric Radiation Measurement (ARM) North Slope of Alaska– Adjacent Arctic Ocean (NSA-AAO) site near Barrow, Alaska. Profiles of precipitation characteristic size are obtained by developing a re...
