The interactions between ULF waves and cold charged particles in the Earth's magnetosphere

地球与行星物理论评, 2022
In the solar wind-magnetosphere coupling processes, many kinds of plasma waves can be excited in the Earth's magnetosphere including ULF waves, hiss waves, chorus waves, etc. Among these waves, ULF waves are featured by the lowest wave frequency (1 mHz～1

Analysis of Chorus Wave Power on Burst‐Mode Timescales During the Van Allen Probes Era

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract Interactions between whistler‐mode chorus waves and electrons are a key driver of dynamics in Earth's radiation belts. These global dynamics are often described using Fokker‐Planck diffusion models. Whilst, in many cases, such models effectively describe the large scale changes within the region, they often rely upon spatially and temporally ...

Validation of VERB‐3D Simulation Results in Response to the COSPAR ISWAT Challenge

Space Weather, Volume 24, Issue 5, May 2026.
Abstract In response to the first long‐term simulation challenge issued by the COSPAR International Space Weather Action Team (ISWAT) G3‐04 team (“Internal Charging Effects and the Relevant Space Environment”), we evaluate the performance of the Versatile Electron Radiation Belt‐3D model by simulating the radiation belt electron dynamics for the entire

Magnetospherically reflected whistlers as a source of plasmaspheric hiss

Geophysical Research Letters, 1992
Ray‐tracing simulations and estimates of whistler wave damping show that magnetospherically reflected whistlers can persist for ∼102 s in a low frequency band (ƒ ∼1 kHz). The combined contribution from whistler rays produced by a single lightning flash but entering the magnetosphere at different points form a continuous hiss‐like signal, as observed at

Cross Correlation Between Plasmaspheric Hiss Waves and Enhanced Radiation Levels at Aviation Altitudes

Space Weather
Enhanced radiation in the Earth's atmosphere can pose serious hazards to pilots, aircraft passengers, and commercial space travelers. Recent results have shown, statistically, that there is a strong correlation between dose rates observed by Automated ...

Enhanced Radiation Levels at Aviation Altitudes and Their Relationship to Plasma Waves in the Inner Magnetosphere

Space Weather, 2023
It is believed that galactic cosmic rays and solar energetic particles are the two major sources of ionizing radiation. However, the radiation source may also be due to relativistic electrons that are associated with precipitation from the Van Allen ...

Radial diffusion simulations of the 20 September 2007 radiation belt dropout [PDF]

Annales Geophysicae, 2014
This is a study of a dropout of radiation belt electrons, associated with an isolated solar wind density pulse on 20 September 2007, as seen by the solid-state telescopes (SST) detectors on THEMIS (Time History of Events and Macroscale Interactions ...

Quasi‐Trapped Zebra Stripes: Radial Transport Driven by Dual‐Pulse Electric Fields

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Energetic electron spectra in Earth's inner radiation belt often exhibit regular stripe‐like features, known as “zebra stripes,” which are typically attributed to the drift motion of stably‐trapped electrons disturbed by electric field perturbations.

Amplification of whistler‐mode hiss inside the plasmasphere [PDF]

Geophysical Research Letters, 2012
Chorus generated outside the plasmasphere has been suggested to be the source of plasmaspheric hiss. A detailed evaluation of the propagation and Landau damping of chorus waves can account for most of the properties of dayside hiss, but the intensity is underestimated by 10–20 dB compared to the observed hiss intensity.

Hiss Wave Evolution During Substorms Based on Van Allen Probes Observations

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract 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) to electron injections during substorms, their evolution across various substorm phases ...
