Using the cold plasma dispersion relation and whistler mode waves to quantify the antenna sheath impedance of the Van Allen Probes EFW instrument [PDF]

, 2016
Cold plasma theory and parallel wave propagation are often assumed when approximating the whistler mode magnetic field wave power from electric field observations.

Statistical Survey of Fast Magnetosonic Waves in the L < 2 Region

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract Fast magnetosonic waves are electromagnetic waves with frequencies ranging from a few Hertz to several hundred Hertz, observed primarily near the magnetic equator. Recent studies demonstrate that magnetosonic waves can propagate into the L<2 $L< 2$ region, while their distributions and propagation properties there remain unclear.

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.

Periodic Response of Plasmasphere to Solar Wind High‐Speed Streams

Geophysical Research Letters, Volume 52, Issue 21, 16 November 2025.
Abstract We report the first observation of the plasmasphere's periodic response to solar wind high‐speed streams (HSS) during the declining phase of Solar Cycle 23, based on plasmapause location data from the IMAGE and THEMIS satellites. In both 2005 and 2008, the daily variability of the plasmapause exhibits a strong anti‐correlation with solar wind ...

Nightside Plasmaspheric Plume‐To‐Core Migration of Whistler‐Mode Hiss Waves

Geophysical Research Letters, 2022
AbstractWhistler‐mode hiss waves play an important role in the radiation belt electron depletion. Whether the hiss waves with significant differences in amplitude and propagation direction within the plasmaspheric core and plume are related to each other remains unclear.

Unraveling the Mystery of Earth's Space Radiation Environment Loss Processes: Meeting Report

Earth and Space Science, Volume 12, Issue 11, November 2025.
Abstract On 10 June and 27 September 2024, two workshops were held at GFZ Potsdam under the umbrella of the Geo. X Research Network of Geosciences to discuss the unresolved question of the overestimation and lack of scattering of modeled ring current electrons during geomagnetic storms.

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.

Statistics of whistler mode waves in the outer radiation belt: Cluster STAFF-SA measurements [PDF]

, 2013
International audience[1] ELF/VLF waves play a crucial role in the dynamics of the radiation belts and are partly responsible for the main losses and the acceleration of energetic electrons.

Interpolating Electron Diffusion Coefficients in Earth's Radiation Belts: A Neural Network Model Inspired by Video Frame Interpolation

Space Weather, Volume 23, Issue 11, November 2025.
Abstract Many numerical models have been built to uncover the physical mechanisms governing radiation belt dynamics and enable real‐time forecasting. The diffusion coefficient, as a critical input for these models, is usually obtained through linear interpolation from precomputed diffusion coefficient libraries.

Constructing the frequency and wave normal distribution of whistler-mode wave power [PDF]

, 2013
We introduce a new methodology that allows the construction of wave frequency distributions due to growing incoherent whistler-mode waves in the magnetosphere. The technique combines the equations of geometric optics (i.e.
