Ionosphere/Plasmasphere sounding with ground and space-based GNSS observations [PDF]

, 2016
Applying a methodology developed and tested in previous studies, the contribution from the ionospheric and plasmaspheric regions to the total electron content (measured by ground receivers) is analyzed.

Plasmaspheric electron content

Geofísica Internacional, 1979
A pesar del abundante trabajo realizado sobre el problema del contenido electrónico plasmasférico y sobre flujos relevantes de plasmas fríos, existen solamente pocas determinaciones experimentales directas de estos conceptos.1. Sondeos ionosféricos (ionosondas terrestres y a bordo de satelites, mediciones de radar en experimentos de dispersión ...

Derivation of Ambient Electron Density Using Spacecraft Potential Measurements From the MMS and Van Allen Satellites: Application to the Plasmasphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract We investigate the empirical relationship between the spacecraft potential (Vs) measured by the Electric Field Double Probes, and the electron density (Ne) measured by the Fast Plasma Instrument on the MMS spacecraft. We derive their relationship during fast‐mode intervals when the Active Spacecraft Potential Control Devices are off.

Photoelectron flux buildup in the plasmasphere

Journal of Geophysical Research: Space Physics, 1978
Processes which confine photoelectrons to the plasmasphere (e.g., collisional backscattering from the thermosphere and magnetic trapping due to pitch angle redistribution through Coulomb collisions in the plasmasphere) tend to increase the steady state photoelectron flux in the plasmasphere above the amplitude level that would otherwise have been ...

Topside Ionization and Effect on Altitudinal Evolution of Nocturnal Ionospheric Irregularities

Space Weather, Volume 24, Issue 1, January 2026.
Abstract Topside ionospheric electron density (Ne) and its control on the variabilities in nocturnal ionospheric irregularities is examined globally using electron density measurements from COSMIC‐2 and Swarm satellite, along with the Swarm satellite‐based Ionospheric Plasma Irregularity (IPIR) index for low and high solar activity (LSA and HSA ...

Unraveling Jupiter's Enigmatic Ionosphere: Evidence of Magnetically‐Controlled Wind‐Driven Dynamics

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract This study investigates the non‐solar trends and variability in Jupiter's sub‐auroral ionosphere from Pioneer, Voyager, Galileo, and Juno radio occultation electron density profiles. We show that these data are correlated with magnetic field geometry via primarily westward and equatorward thermospheric neutral winds driving field‐aligned ...

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.

Cold ions of ionospheric origin observed at the dayside magnetopause and their effects on magnetic reconnection [PDF]

, 2015
Thesis (Ph.D.) University of Alaska Fairbanks, 2015Magnetic reconnection at the dayside magnetopause is one of the most important mechanisms that efficiently transfers solar wind particles, momentum, and energy into the magnetosphere.

Investigation of EMIC wave scattering as the cause for the BARREL 17 January 2013 relativistic electron precipitation event: A quantitative comparison of simulation with observations [PDF]

, 2014
Electromagnetic ion cyclotron (EMIC) waves were observed at multiple observatory locations for several hours on 17 January 2013. During the wave activity period, a duskside relativistic electron precipitation (REP) event was observed by one of the ...

The Global Propagation of Hiss Waves Originating From Dynamic Plasmaspheric Plume

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract Hiss waves play a critical role in shaping Earth's radiation belts and mediating magnetosphere‐ionosphere energy transfer. Intense hiss emissions are frequently generated within dynamic plasmaspheric plumes through linear and nonlinear wave‐particle interactions.
