A DE-1/whistler study of the thermal plasma structure and dynamics in the dusk bulge sector of the magnetosphere [PDF]

The objective of this research was to obtain new understanding of the thermal plasma structure and dynamics of the plasmasphere bulge region of the magnetosphere, with special emphasis on the erosion process that results in a reduction in plasmasphere ...

A new electron density model of the plasmasphere for operational applications and services

Journal of Space Weather and Space Climate, 2018
The Earth's plasmasphere contributes essentially to total electron content (TEC) measurements from ground or satellite platforms. Furthermore, as an integral part of space weather, associated plasmaspheric phenomena must be addressed in conjunction with ...

Energetic, relativistic and ultra-relativistic electrons: Comparison of long-term VERB code simulations with Van Allen Probes measurements [PDF]

, 2015
In this study, we compare long-term simulations performed by the Versatile Electron Radiation Belt (VERB) code with observations from the Magnetic Electron Ion Spectrometer and Relativistic Electron-Proton Telescope instruments on the Van Allen Probes ...

Automatic Detection of Lightning Whistlers Observed by the Plasma Wave Experiment Onboard the Arase Satellite Using the OpenCV Library

Remote Sensing, 2019
The automatic detection of shapes or patterns represented by signals captured from spacecraft data is essential to revealing interesting phenomena. A signal processing approach is generally used to extract useful information from observation data.

Isolated cold plasma regions: Observations and their relation to possible production mechanisms [PDF]

Regions of enhanced cold plasma, isolated from the main plasmasphere along the Explorer 45 orbit on the equatorial plane, are reported using the sheath induced potentials seen by the electric field experiment. The occurrence of these regions has a strong

Modeling of the Plasmasphere Dynamics

, 2020
Die Plasmasphäre ist eine die Erde umgebende dynamische Region aus kaltem, dichtem Plasma. Ihre Form und Größe sind sehr anfällig für Schwankungen der solaren und geomagnetischen Bedingungen. Ein präzises Modell der Plasmadichte in der Plasmasphäre ist wichtig für die GNSS-Navigation und für die Vorhersage gefährlicher Auswirkungen der kosmischen ...

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 ...
