The plasmapause revisited [PDF]

open access: green, 1976
Saturation of the dc double probe instrument on Explorer 45 was used to identify the plasmapause. A data base was developed to statistically study the average position of the plasmapause over 14.5 hours of magnetic local time under differing magnetic ...

Proposal for an ionosphere/plasmasphere monitoring system [PDF]

open access: yesAnnales Geophysicae, 1994
A space-based satellite system suited for long-term monitoring of the Earth's ionosphere/plasmasphere systems is proposed. The monitoring system consists of a network of radio beacon satellites capable of measuring the ionospheric and plasmaspheric ...

The trapping of equatorial magnetosonic waves in the Earth’s outer plasmasphere [PDF]

open access: yes, 2014
We investigate the excitation and propagation of equatorial magnetosonic waves observed by the Van Allen Probes and describe evidence for a trapping mechanism for magnetosonic waves in the Earth\u27s plasmasphere.

Dynamical Simulations of Plasmapause Deformations [PDF]

open access: yesSpace Science Reviews, 2006
Dynamical simulations have been developed at IASB-BIRA to model the deformations of the plasmasphere during geomagnetic substorms and other variations in the level of geomagnetic activity. The simulations are based on the mechanism of plasma instability and use the empirical Kp-dependent electric field E5D.

Modulation of NTC frequencies by Pc5 ULF pulsations : experimental test of the generation mechanism and magnetoseismology of the emitting surface [PDF]

open access: yes, 2009
Nonthermal continuum (NTC) radiation is believed to be emitted by the conversion of an electrostatic wave into an electromagnetic one, which takes place at the Earth's magnetic equator.

Evaluating the performance of empirical models of total electron density and whistler-mode wave amplitude in the Earth’s inner magnetosphere

open access: yesFrontiers in Astronomy and Space Sciences, 2023
Empirical models have been previously developed using the large dataset of satellite observations to obtain the global distributions of total electron density and whistler-mode wave power, which are important in modeling radiation belt dynamics.

Off‐Equatorial Pi2 Pulsations Inside and Outside the Plasmapause Observed by the Arase Satellite

open access: yesJournal of Geophysical Research: Space Physics, 2021
Using magnetic field and electron density data from the Arase satellite for the period from March 2017 to September 2019, we investigate the spatial properties of Pi2 pulsations in relation to the plasmapause over a wide latitudinal range (absolute ...

Comparisons between EUV/IMAGE observations and numerical simulations of the plasmapause formation [PDF]

open access: yesAnnales Geophysicae, 2005
Simulations of plasmapause formation described in Pierrard and Lemaire (2004) predict the shape and equatorial distance of the plasmapause as a function of the geomagnetic activity index Kp.

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]

open access: yes, 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 ...
