The Global Propagation of Hiss Waves Originating From Dynamic Plasmaspheric Plume

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract Hiss waves play a critical role in shaping Earth's radiation belts and mediating magnetosphere‐ionosphere energy transfer. Intense hiss emissions are frequently generated within dynamic plasmaspheric plumes through linear and nonlinear wave‐particle interactions.

Electron losses from the radiation belts caused by EMIC waves [PDF]

, 2014
Electromagnetic Ion Cyclotron (EMIC) waves cause electron loss in the radiation belts by resonating with high energy electrons at energies greater than about 500 keV. However, their effectiveness has not been fully quantified.

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 ...

The Roles of Transport and Wave-Particle Interactions on Radiation Belt Dynamics [PDF]

, 2011
Particle fluxes in the radiation belts can vary dramatically during geomagnetic active periods. Transport and wave-particle interactions are believed to be the two main types of mechanisms that control the radiation belt dynamics.

The parameterization of wave-particle interactions in the Outer Radiation Belt [PDF]

, 2017
We explore the use of mean-value empirical wave models in diffusion models of the Outer Radiation Belt. We show that magnetospheric wave power is not normally-distributed in time and that geomagnetic activity does not provide a deterministic proxy for ...

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

Journal of Geophysical Research: Space Physics, 2015
AbstractPlasmaspheric 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 statistical models of wave observations that may not accurately reproduce the instantaneous ...

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.

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.

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 ...

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.
