Van Allen Probes Observations of Oxygen Ions at the Geospace Plume
Frontiers in Astronomy and Space Sciences, 2021 The geospace plume couples the ionosphere, plasmasphere, and magnetosphere from sub-auroral regions to the magnetopause, on polar field lines, and into the magnetotail.

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 ...

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.

Fully Kinetic Simulations of Ion‐Acoustic Waves in Asymmetric Reconnection With Cold Ions
Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.Abstract In collisionless plasma, ion‐acoustic wave (IAW) is an important candidate for enhancing resistivity and viscosity, yet their presence and role in magnetic reconnection remain poorly understood. Here, we employ 2.5‐D particle‐in‐cell simulations to investigate IAWs in asymmetric magnetopause reconnection involving a cold ion population ...

Hiss Wave Evolution During Substorms Based on Van Allen Probes Observations
Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.Abstract Hiss waves frequently occur in the plasmasphere or plumes, playing a key role in energetic electron loss in the Earth's inner magnetosphere. While previous studies have linked hiss wave enhancements in the outer plasmasphere (just inside the plasmapause) to electron injections during substorms, their evolution across various substorm phases ...

Abrupt Disappearance of Plasmaspheric Hiss Inside the Magnetic Dip
Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.Abstract Plasmaspheric hiss plays an important role in radiation belt electron dynamics, and its excitation and propagation have long attracted attention. During a substorm, Van Allen Probe B observed the disappearance of plasmaspheric hiss at the magnetic dip, which was driven by the injection of energetic protons.

SAMI3 simulation of plasmasphere refilling [PDF]
Geophysical Research Letters, 2013 The Naval Research Laboratory three‐dimensional, first‐principles simulation code SAMI3 (Sami3 is Also a Model of the Ionosphere) is used to model plasmasphere refilling. A time‐dependent Volland‐Stern‐Maynard‐Chen potential is used to model an idealized magnetic storm that erodes the plasmasphere to L<3.

Effects of argon ion injections in the plasmasphere [PDF]
, 1980 In lifting massive space power system payloads from low Earth orbit to geosynchronous Earth orbit, Cargo Orbit Transfer (COTV) using ion propulsion will inject energetic beams of argon ions into the plasmasphere.
