The Plasmasphere Boundary Layer [PDF]
Annales Geophysicae, 2004 As an inner magnetospheric phenomenon the plasmapause region is of interest for a number of reasons, one being the occurrence there of geophysically important interactions between the plasmas of the hot plasma sheet and of the cool plasmasphere. There

Density structures inside the plasmasphere: Cluster observations [PDF]
Annales Geophysicae, 2004 The electron density profiles derived from the EFW and WHISPER instruments on board the four Cluster spacecraft reveal density structures inside the plasmasphere and at its outer boundary, the plasmapause.

The effect of disturbed-time electric fields on the inner plasmasphere [PDF]
Annales Geophysicae, 1994 Results from a mathematical model provide a description of the mid-latitude, low L-shell ionosphere and plasmasphere. Variations in the composition and dynamics of the plasmasphere and changes in the nature of the coupling between the plasmasphere and

Recirculation of plasmasphere material during idealized magnetic storms
Frontiers in Physics, 2023 The fate of flux tube material once it is eroded from of the plasmasphere through a dayside plume remains unknown. The eroded plasmasphere material can be either swept away by the solar wind and lost from Earth’s system, or recirculated into the inner ...

Modeling the plasmasphere with SAMI3 [PDF]
Geophysical Research Letters, 2013 The study of the plasmasphere is extremely important to understanding space weather phenomena; for example, it plays a critical role in the regulation of radiation belt dynamics. In this paper, the first 3D simulation of the plasmasphere based on the first‐principles physics model SAMI3 is presented.

A plasmaspheric cavity resonance in a longitudinally non-uniform plasmasphere [PDF]
Earth, Planets and Space, 2014 Power spectra of a plasmaspheric cavity resonance (strictly, a plasmaspheric virtual resonance) in a longitudinally non-uniform plasmasphere are calculated. It is shown that the spectra depend on longitude. Therefore, a cavity resonance mode can have local time depending spectra when the plasmasphere is non-uniform in a longitudinal direction.

Determining Plasmaspheric Densities from Observations of Plasmaspheric Hiss [PDF]
Journal of Geophysical Research: Space Physics, 2018 AbstractA new method of inferring electron plasma densities inside of the plasmasphere is presented. Utilizing observations of the electric and magnetic field wave power associated with plasmaspheric hiss, coupled with the cold plasma dispersion relation, permits calculation of the plasma density.
