Argon-ion contamination of the plasmasphere [PDF]

, 1979
This paper applies present observational and analytic knowledge on effects of plasma beam interaction wth the magnetosphere to the plasmasphere contamination problem of the argon ion engine exhaust expected to be deposited in the magnetosphere during the

The effect of disturbed-time electric fields on the inner plasmasphere

Annales Geophysicae
Results from a mathematical model provide a description of the mid-latitude, low <i>L</i>-shell ionosphere and plasmasphere. Variations in the composition and dynamics of the plasmasphere and changes in the nature of the coupling between the ...

Models for plasmasphere and plasmatrough density and average ion mass including dependence on L, MLT, geomagnetic activity, and phase of the solar cycle

Frontiers in Astronomy and Space Sciences
Using observations of mass density inferred from standing Alfvén wave frequencies and electron density inferred from plasma wave frequencies, predominantly for the Combined Release and Radiation Effects Satellite (CRRES) and Van Allen Probes spacecraft ...

Outer Plasmasphere Irregularities and Plasmatails

, 1974
Examples of OGO-5 and OGO-3 ion spectrometer measurements of light ion density irregularities in and/or beyond the outer plasmasphere at different local times are compared to the expected plasmasphere evolution based on a simple convection model.

Coincident Observations by the Kharkiv IS Radar and Ionosonde, DMSP and Arase (ERG) Satellites, and FLIP Model Simulations: Implications for the NRLMSISE‐00 Hydrogen Density, Plasmasphere, and Ionosphere

Geophysical Research Letters, 2018
This paper reports the results of ionosphere and plasmasphere observations with the Kharkiv incoherent scatter radar and ionosonde, Defense Meteorological Satellite Program, and Arase (ERG) satellites and simulations with field line interhemispheric ...

The Real‐Time Advanced Ionospheric Data Assimilation (AIDA) Model

Space Weather
The Advanced Ionospheric Data Assimilation (AIDA) is a real‐time data assimilation model of global 3D ionosphere and plasmasphere electron density. Changes in the local space environment can occur on very short timescales, particularly during disturbed ...

The electron density at the midpoint of the plasmapause

Frontiers in Astronomy and Space Sciences
The high density plasmasphere in the magnetosphere is often separated from a lower density region outside of the plasmasphere, called the plasmatrough, by a sharp gradient in electron density called the plasmapause.

Pre‐Existing Plasmaspheric Density Structure

Geophysical Research Letters
We perform a basic model experiment: we run two nearly identical plasmapause simulations, differing only by their initial conditions. The first run contains initial fine‐scale and mesoscale structure, and the second run is initialized with a featureless,
