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.

Multi‐Species Energy‐Banded Ions in the Ionosphere During the 21 January 2005 Magnetic Storm: Low‐Altitude Edge of the Warm Plasma Cloak

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract During the 21–22 January 2005 magnetic storm, the FAST satellite observed warm (< few keV) ions in discrete energy bands on the dayside at ∼3,000 km altitude for more than 6.5 hr. We suggest that the ionospheric energy‐banded ions represent the low‐altitude edge of the warm plasma cloak observed simultaneously by magnetospheric satellites ...

Electron loss rates from the outer radiation belt caused by the filling of the outer plasmasphere: The calm before the storm [PDF]

, 2009
Measurements from seven spacecraft in geosynchronous orbit are analyzed to determine the decay rate of the number density of the outer electron radiation belt prior to the onset of high-speed-stream-driven geomagnetic storms.

Enhanced Radiation Exposure of Airline Crew and Passengers During the May 2024 Geomagnetic Storm

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Enhanced radiation at aviation altitudes is a concern for flight crew and passengers. During space weather events, solar flares and coronal mass ejection (CME) driven shocks are sources of energetic particles that can reach Earth's near‐space environment and interact with its magnetic field and atmosphere.

Outer Radiation Belt Dynamics During the October 2012 Storm Revisited: Rapid Inward Radial Transport From a Dynamic Outer Boundary

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Earth's outer radiation belt electron flux is highly variable and can be enhanced by over an order of magnitude over timescales less than one day, as observed during the October 2012 storm. Previous studies of this storm (e.g., Reeves et al., 2013, https://doi.org/10.1126/science.1237743) have invoked local acceleration to explain this ...

Highly anisotropic distribution of energetic electrons and triggered VLF emissions

, 2001
The work considers the highly anisotropic electron distribution functions observed by Bell and co-workers at Stanford in the magnetosphere. IOt is maintained that Bells' observations provide evidence for the existence of step like deformations in ...

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.

Three dimensional electron radiation belt simulations using the BAS Radiation Belt Model with new diffusion models for chorus, plasmaspheric hiss and lightning-generated whistlers [PDF]

, 2014
The flux of relativistic electrons in the Earth's radiation belts is highly variable and can change by orders of magnitude on timescales of a few hours. Understanding the drivers for these changes is important as energetic electrons can damage satellites.

A statistical analysis of the global distribution of plasmaspheric hiss based on Van Allen Probes wave observations

Acta Physica Sinica, 2017
Plasmaspheric hiss plays an important role in driving the precipitation loss of radiation belt electrons via pitch angle scattering, which is also known as the major cause of the formation of the slot region between the inner and outer radiation belt. Therefore, it is of scientific importance to acquire a complete picture of the global distribution of ...
