Quantification of Energetic Electron Precipitation Driven by Plume Whistler Mode Waves, Plasmaspheric Hiss, and Exohiss [PDF]

Geophysical Research Letters, 2019
AbstractWhistler mode waves are important for precipitating energetic electrons into Earth's upper atmosphere, while the quantitative effect of each type of whistler mode wave on electron precipitation is not well understood. In this letter, we evaluate energetic electron precipitation driven by three types of whistler mode waves: plume whistler mode ...

Three-dimensional ray tracing of VLF waves in a magnetospheric environment containing a plasmaspheric plume [PDF]

, 2009
A three dimensional ray tracing of whistler-mode chorus is performed in a realistic magnetosphere using the HOTRAY code. A variety of important propagation characteristics are revealed associated with azimuthal density gradients and a plasmaspheric plume.

Identification of Locally Generated Plasmaspheric Hiss

Geophysical Research Letters
In this study, we statistically analyze the wave properties of plasmaspheric hiss using data from the Van Allen Probes. The magnetic power spectral densities of hiss waves exhibit dependence on magnetic local time, geomagnetic activity, and the L‐shell ...

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.

Quantifying the Effect of Plasmaspheric Hiss on the Electron Loss From the Slot Region

, 2020
We present global statistical models of both wave amplitude and wave normal angle (WNA) of plasmaspheric hiss using Van Allen Probe-A observations. They utilize the time history of solar wind parameters, that is, interplanetary magnetic field B-Z and ...

Frequency‐Drifting Plasmaspheric Hiss: A Statistical Study From the Van Allen Probes Data

Geophysical Research Letters
Plasmaspheric hiss, a whistler‐mode emission confined in the high‐density plasmasphere, is of great interest to the space community attributed to its important role in inner magnetospheric dynamics.

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 ...

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 ...

Analysis of plasmaspheric hiss wave amplitudes inferred from low‐altitude POES electron data: Validation with conjunctive Van Allen Probes observations [PDF]

, 2015
Plasmaspheric hiss plays an important role in controlling the overall structure and dynamics of the Earth's radiation belts. The interaction of plasmaspheric hiss with radiation belt electrons is commonly evaluated using diffusion codes, which rely on ...

VLF waves from ground‐based transmitters observed by the Van Allen Probes: Statistical model and effects on plasmaspheric electrons

Geophysical Research Letters, 2017
Whistler mode very low frequency (VLF) waves from powerful ground‐based transmitters can resonantly scatter energetic plasmaspheric electrons and precipitate them into the atmosphere.
