Sub‐MeV Electron Precipitation Driven by EMIC Waves: New Insights From CIRBE/REPTile‐2 Measurements

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Electromagnetic ion cyclotron (EMIC) waves are recognized as a key driver of relativistic (>1 MeV) electron loss in Earth's magnetosphere. Growing evidence also suggests that EMIC wave can efficiently scatter sub‐MeV electrons, although the precise energy range and the underlying physical mechanisms remain debated.

Analysis of the effect of cosmic noise absorption increase on propagation of auroral hiss to the ground

Solar-Terrestrial Physics
We analyze the effect of changes in the cosmic radio noise absorption in the lower ionosphere on propagation of the auroral hiss to the ground, using observational data from the Lovozero and Tumanny observatories.

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 ...

Abrupt Disappearance of Plasmaspheric Hiss Inside the Magnetic Dip

Geophysical Research Letters
Plasmaspheric hiss plays an important role in radiation belt electron dynamics, and its excitation and propagation have long attracted attention. During a substorm, Van Allen Probe B observed the disappearance of plasmaspheric hiss at the magnetic dip ...

Direction finding of auroral VLF hiss in auroral zone

Antarctic Record, 1981
A newly developed direction finding ('DF') for auroral hiss based on the measurement of time differences of wave arrival among three spaced points was carried out around Syowa Station (geomag. lat. -70.4°), Antarctica in 1978-1979. It has been found that

A Wave Model and Diffusion Coefficients for Plasmaspheric Hiss Parameterized by Plasmapause Location

Journal of Geophysical Research: Space Physics, 2019
The scattering of electrons via plasmaspheric hiss whistler‐mode plasma waves has profound consequences for the dynamics of electrons in the inner terrestrial magnetosphere, including the radiation belts. Consequently, simulations of inner magnetospheric

Variability of Quasilinear Diffusion Coefficients for Plasmaspheric Hiss

Journal of Geophysical Research: Space Physics, 2019
In the outer radiation belt, the acceleration and loss of high‐energy electrons is largely controlled by wave‐particle interactions. Quasilinear diffusion coefficients are an efficient way to capture the small‐scale physics of wave‐particle interactions ...

Evolution of Radiation Belt Electron Pitch Angle Distribution Due to Combined Scattering by Plasmaspheric Hiss and Magnetosonic Waves

Geophysical Research Letters, 2019
Both magnetosonic (MS) waves and plasmaspheric hiss can resonantly scatter outer radiation belt electrons, leading to various electron pitch angle distribution.
