Dependence of Plasmaspheric Hiss Power on ωpe/Ωce

Geophysical Research Letters
Plasmaspheric hiss waves play a key role in scattering energetic electrons and are often modeled in the inner magnetosphere using empirical hiss power maps parameterized by L shell.

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 ...

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 ...

Analysis of plasmaspheric hiss wave amplitudes inferred from low‐altitude POES electron data: Technique sensitivity analysis [PDF]

Journal of Geophysical Research: Space Physics, 2015
AbstractA novel technique capable of inferring wave amplitudes from low‐altitude electron measurements from the Polar Operational Environmental Satellites (POES) spacecraft has been previously proposed to construct a global dynamic model of chorus and plasmaspheric hiss waves.

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

Suprathermal Electron Evolution Under the Competition Between Plasmaspheric Plume Hiss Wave Heating and Collisional Cooling

Geophysical Research Letters, 2020
AbstractSuprathermal electrons are a major heat source of ionospheric plasma. How the suprathermal electrons evolve during their bounces inside the plasmasphere is a fundamental question for the magnetosphere‐ionosphere coupling. On the basis of Van Allen Probes observations and quasi‐linear simulations, we present here the first quantitative study on ...

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.

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 ...

Energetic Electron Diffusion and Precipitation Driven by Ducted Hiss Waves in High Density Irregular Region

Geophysical Research Letters
Plasmaspheric hiss plays an important role in the electron precipitation and the slot formation in radiation belts. Recent studies show the whistler‐mode waves can be guided in the density irregularities, performing parallel propagation.

Enabling High‐Fidelity Wave‐Particle Interaction Studies: A Novel Filtering for Isolating Whistlers From Spacecraft Noise

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Resolving the mixture of natural plasma waves and persistent spacecraft interference is a fundamental challenge in space physics, as it obstructs the analysis of wave‐particle interactions and energy transport processes. Traditional signal decomposition methods often fail to adequately separate these components due to their time‐varying ...
