Observations of the Electrodynamical Ties Between Sporadic E and the Plasmasphere

Earth and Space Science, 2020
A joint investigation was conducted of coherent backscatter radar observations of irregularities within the E and F regions and tomographic mapping of corotating plasmaspheric irregularities (CPIs) near Japan and the American northwest from June 2018 ...

Investigation of the single layer model of GPS ionospheric data processing using IRI-90 and the attached diffusive equilibrium model of plasmaspheric electron density

Annals of Geophysics, 1997
The single layer model of GPS ionospheric data processing is compared with the International Reference Ionosphere í 1990 and the attached Diffusive Equilibrium model of Plasmasphere (IRI-90+DEP) which proved to be a good supplement to GPS data processing.

Electron Scattering by Highly Oblique Quasi‐Electrostatic Chorus Waves Under Realistic Magnetospheric Conditions

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Using Van Allen Probes data (2013–2015), we report that highly oblique chorus waves frequently occur in low‐density regions where fpe/fce≈3 ${f}_{\text{pe}}/{f}_{\text{ce}}\approx 3$. These waves exhibit an electric‐to‐magnetic energy ratio PE/c2PB>0.5 $\sqrt{{P}_{\mathrm{E}}/{c}^{2}{P}_{\mathrm{B}}} > 0.5$, much higher than the typical <0.1 ${

Proposal for an ionosphere/plasmasphere monitoring system

Annales Geophysicae, 1994
Abstract. A space-based satellite system suited for long-term monitoring of the Earth's ionosphere/plasmasphere systems is proposed. The monitoring system consists of a network of radio beacon satellites capable of measuring the ionospheric and plasmaspheric electron content on a continuous base with high time resolution.

Origins of plasmaspheric hiss [PDF]

Journal of Geophysical Research: Space Physics, 2006
Plasmaspheric hiss is an electromagnetic wave emission responsible for electron loss from the radiation belts, particularly in the slot region (2 < L < 3). There are two leading theories for the origin of plasmaspheric hiss: in situ amplification of wave turbulence in space and lightning‐generated whistlers.

Bounce Resonance Between ULF Waves and Electrons in the Dayside Outer Magnetosphere

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Resonant interactions between ultra‐low‐frequency (ULF) waves and particles are critical for energy transfer in the Earth's magnetosphere, and have been extensively investigated in the inner magnetosphere. However, resonant processes between ULF waves and electrons in the dayside outer magnetosphere remain largely unexplored.

Generation of plasmaspheric undulations [PDF]

Geophysical Research Letters, 2008
We have modeled the plasmaspheric plume region using the Comprehensive Ring Current model (CRCM) and the Dynamical Global Core Plasma model (DGCPM), for an event that exhibited substantial undulations or ripples as observed by the IMAGE EUV imager during 17 April 2002. We drove the simulated electric field using the Weimer cross polar cap potential. We
