Nonlinear Electron Interactions With Intense VLF Waves From Transmitters

Journal of Geophysical Research: Space Physics, Volume 130, Issue 12, December 2025.
Abstract The impact on electron lifetimes of nonlinear interactions with the most intense very low frequency (VLF) waves from transmitters has hitherto been neglected in radiation belt codes. Here, we show the presence of a small population of intense wave packets, originating from ground‐based VLF transmitters and reaching 10 mV/m around the magnetic ...

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.

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 ...

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.

A case study of electron precipitation fluxes due to plasmaspheric hiss [PDF]

, 2015
We find that during a large geomagnetic storm in October 2011 the trapped fluxes of >30, >100, and >300 keV outer radiation belt electrons were enhanced at L=3-4 during the storm main phase.

Radial and Latitudinal Distributions of the Exohiss Under the Effect of Landau Damping

Geophysical Research Letters
Exohiss serves as a typical imprint of the outward energy release from plasmaspheric hiss. The distribution of exohiss under the effect of Landau damping has not been thoroughly evaluate.

Energetic electron precipitation during substorm injection events: High-latitude fluxes and an unexpected midlatitude signature [PDF]

, 2008
Geosynchronous Los Alamos National Laboratory (LANL-97A) satellite particle data, riometer data, and radio wave data recorded at high geomagnetic latitudes in the region south of Australia and New Zealand are used to perform the first complete modeling ...
