Local Generation of High‐Frequency Plasmaspheric Hiss Observed by Van Allen Probes

Geophysical Research Letters, 2019
The generation of a high‐frequency plasmaspheric hiss (HFPH) wave observed by Van Allen Probes is studied in this letter for the first time. The wave has a moderate power spectral density (∼10−6 nT2/Hz), with a frequency range extended from 2 to 10 kHz ...

Plasma Wave Measurements from the Van Allen Probes

, 2014
The twin Van Allen Probes spacecraft were launched on August 30, 2012 to study the Earth's Van Allen radiation belts. The Electric and Magnetic Field Instrument Suite and Integrated Science (EMFISIS) investigation includes a plasma wave instrument (Waves) that simultaneously measures three orthogonal components of the wave magnetic field from ~10 Hz to

Reproducing the observed energy‐dependent structure of Earth's electron radiation belts during storm recovery with an event‐specific diffusion model

Geophysical Research Letters, 2016
We present dynamic simulations of energy‐dependent losses in the radiation belt “slot region” and the formation of the two‐belt structure for the quiet days after the 1 March storm.

Hiss Wave Evolution During Substorms Based on Van Allen Probes Observations

Geophysical Research Letters
Hiss waves frequently occur in the plasmasphere or plumes, playing a key role in energetic electron loss in the Earth's inner magnetosphere. While previous studies have linked hiss wave enhancements in the outer plasmasphere (just inside the plasmapause)

Pi2 Pulsations During Extremely Quiet Geomagnetic Condition: Van Allen Probe Observations

Journal of Astronomy and Space Sciences, 2017
A ultra low frequency (ULF) wave, Pi2, has been reported to occur during periods of extremely quiet magnetospheric and solar wind conditions. And no statistical study on the Pi2 has been performed during extremely quiet conditions, using satellite observations to the author’s knowledge.

EMIC Wave Distributions Observed by the Van Allen Probes

, 2019
Characteristics of electromagnetic ion cyclotron (EMIC) waves detected by the Van Allen probes are statistically analyzed, particularly wave-band, bandwidth, and time duration. The Electric and Magnetic Field Instrument Suite and Integrated Science, an instrument on board the Van Allen Probes, provides the necessary magnetic field measurements to ...

Magnetospheric Line Radiation: Temporal Modulation Corresponding to a Bouncing Wave

Geophysical Research Letters
Magnetospheric line radiation (MLR) is a peculiar type of whistler‐mode emissions formed by several similarly spaced spectral lines, whose frequencies may vary with time.
