VLF Transmitters as Tools for Monitoring the Plasmasphere [PDF]

Journal of Geophysical Research: Space Physics, 2018
AbstractContinuous burst mode very low frequency (VLF) measurements were recorded on the Van Allen Probes satellites and are analyzed to detect pulses from the Russian Alpha (RSDN‐20) ground‐based navigational system between January and March 2016. Based on the wave characteristics of these pulses and on the position of the spacecraft, the signals ...

Inner Magnetospheric Oxygen Torus Induced by Electromagnetic Ion Cyclotron Waves

Geophysical Research Letters
Cold oxygen ions escaping from the ionosphere and temporarily trapped near the plasmapause form the oxygen torus. Mass‐loading by these oxygen ions significantly affects magnetospheric plasma processes.

Global Effects of Chorus and Hiss Waves on Trapped Energetic Electrons at Jupiter

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Unlike Earth, where whistler‐mode chorus is generally observed outside the plasmasphere and hiss is predominantly confined within it, Jupiter's magnetosphere frequently hosts both wave modes simultaneously. Using Juno observations, we present a global survey of whistler‐mode waves at Jupiter, demonstrating that both chorus and hiss are ...

Chorus acceleration of radiation belt relativistic electrons during March 2013 geomagnetic storm [PDF]

, 2014
The recent launching of Van Allen probes provides an unprecedent opportunity to investigate variations of the radiation belt relativistic electrons. During the 17-19 March 2013 storm, the Van Allen probes simultaneously detected strong chorus waves and ...

A New Global Climatological Model of the Equatorial Ionospheric Vertical E × B Drift: Integrating Ground‐Based Magnetometer, Radar, and Satellite Data Sets

Earth and Space Science, Volume 13, Issue 4, April 2026.
Abstract We present a new empirical vertical E×B $\mathbf{E}\times \mathbf{B}$ drift model developed using ground‐based magnetometer, radar, and satellite data over equatorial latitude regions. We first implement an algorithm relating magnetometer derived equatorial electrojet (EEJ) and vertical ion plasma drift (equivalent to vertical E×B $\mathbf{E ...

Studies of the structure of the plasmasphere as seen by radiosounder measurements aboard the Alovetti-satellite [PDF]

The structure of the plasmasphere was studied as seen by radiosounder measurements aboard the Alovetti-2 satellite. Magnetic tape data files were obtained from the NASA Ames Research Center to give a reasonably complete set of high latitude electron ...

A Computationally Efficient Method for Deriving Instantaneous F2 Layer Peak Parameters From Climatological Maps and TEC Observations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract International Reference Ionosphere (IRI) and the Ionosphere‐Plasmasphere (IRI‐Plas) models describe monthly median ionospheric conditions. IRI‐Plas, unlike IRI, allows one to include instantaneous Total Electron Content observations (TEC) to adjust the median predictions. The standard IRI‐Plas generates monthly medians of foF2m, hmF2m and TECm

The magnetospheric plasma tail [PDF]

The structural nature of the earth's plasmasphere at onset and immediately following an intense magnetic storm is examined. Thermal proton density measurements by the RF ion mass spectrometer on the low altitude polar orbiting satellite OGO-4 were ...

Resonant scattering of energetic electrons by unusual low-frequency hiss [PDF]

, 2014
We quantify the resonant scattering effects of the unusual low-frequency dawnside plasmaspheric hiss observed on 30 September 2012 by the Van Allen Probes. In contrast to normal (∼100-2000 Hz) hiss emissions, this unusual hiss event contained most of its

A New Orthogonal Geomagnetic Coordinate System: The Generalized Eccentric Dipole

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract The study of near‐Earth plasma environment relies heavily on accurate geomagnetic coordinate systems, mainly because the plasma motion is controlled by the E×B $\boldsymbol{E}\times \boldsymbol{B}$ drift and thus is constrained by the structure of the magnetic field.
