Simultaneous observation of chorus and hiss near the plasmapause [PDF]

, 2012
On 4 August 2010 a moderate geomagnetic storm occurred with minimum Dst of −65 nT and maximum Kp of 7−. Shortly after the onset of this storm, VLF chorus was observed at Marion Island (L= 2.6).

Parametric Dependence of Linear and Nonlinear Growth of Whistler‐Mode Chorus Waves

Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract We calculated the linear and nonlinear growth rates of whistler‐mode chorus waves with relativistic treatment across different wave frequencies and investigated their dependence on the associated parameters, including background magnetic field strength, cold electron density, and energetic electron temperature.

Inner magnetospheric plasma interactions and coupling with the ionosphere [PDF]

, 2005
The inner magnetosphere occupies a vast volume in space containing a relatively low-density mixture of hot and cold plasmas: the ring current, plasmasphere and radiation belt.

Multi‐MeV Electron Occurrence and Lifetimes in the Outer Radiation Belt and Slot Region During the Maximum of Solar Cycle 22

Space Weather, Volume 23, Issue 10, October 2025.
Abstract The Combined Release and Radiation Effects Satellite (CRRES) observed the response of the Van Allen radiation belts to peak solar activity within solar cycle 22. This study analyses relativistic and ultra‐relativistic electron occurrence and loss timescales within the CRRES High Energy Electron Fluxometer (HEEF) data set, including during ...

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.

POES satellite observations of EMIC-wave driven relativistic electron precipitation during 1998-2010 [PDF]

, 2013
[1] Using six Polar Orbiting Environmental Satellites (POES) satellites that have carried the Space Environment Module-2 instrument package, a total of 436,422 individual half-orbits between 1998 and 2010 were inspected by an automatic detection ...

Diffuse Auroral Precipitation Effects on Ionospheric Conductance During Magnetic Storms: Comparison of Simulated and Incoherent Radar Scatter‐Inferred Conductance

Journal of Geophysical Research: Space Physics, Volume 130, Issue 9, September 2025.
Abstract We investigated the effects of storm‐time diffuse auroral electron precipitation on ionospheric Pedersen and Hall conductivity and conductance during the CME‐driven St. Patrick's Day storms of 2013 (min Dst = −131 nT) and 2015 (min Dst = −233 nT).

Wave-particle interactions in the outer radiation belts [PDF]

, 2015
Data from the Van Allen Probes have provided the first extensive evidence of non-linear (as opposed to quasi-linear) wave-particle interactions in space with the associated rapid (fraction of a bounce period) electron acceleration to hundreds of keV by ...

Real‐Time Forecasting of Pitch Angle‐Resolved Differential Electron Flux at MEO Using Solar Wind and Geomagnetic Indices

Space Weather, Volume 23, Issue 9, September 2025.
Abstract We present a real‐time operational machine learning model based on convolutional neural network for forecasting pitch angle‐resolved differential electron flux at Medium Earth Orbit (MEO) altitudes in the outer radiation belt. Unlike previous studies, our model is designed for immediate operational use, relying exclusively on real‐time ...

An empirically observed pitch-angle diffusion eigenmode in the Earth\u27s electron belt near L* = 5.0 [PDF]

, 2014
Using data from NASA\u27s Van Allen Probes, we have identified a synchronized exponential decay of electron flux in the outer zone, near L* = 5.0. Exponential decays strongly indicate the presence of a pure eigenmode of a diffusion operator acting in the
