Prediction of Dynamic Plasmapause Location Using a Neural Network

Space Weather, 2021
As a common boundary layer that distinctly separates the regions of high‐density plasmasphere and low‐density plasmatrough, the plasmapause is essential to comprehend the dynamics and variability of the inner magnetosphere.

Statistical study and corresponding evolution of plasmaspheric plumes under different levels of geomagnetic storms [PDF]

Annales Geophysicae, 2022
Using observations of Van Allen Probes, we present a statistical study of plasmaspheric plumes in the inner magnetosphere. Plasmaspheric plumes tend to occur during the recovery phase of geomagnetic storms.

Chorus acceleration of radiation belt relativistic electrons during March 2013 geomagnetic storm [PDF]

, 2014
The recent launching of Van Allen probes provides an unprecedent opportunity to investigate variations of the radiation belt relativistic electrons. During the 17-19 March 2013 storm, the Van Allen probes simultaneously detected strong chorus waves and ...

Intense chorus waves are the cause of flux-limiting in the heart of the outer radiation belt

Scientific Reports, 2022
Chorus waves play a key role in outer Van Allen electron belt dynamics through cyclotron resonance. Here, we use Van Allen Probes data to reveal a new and distinct population of intense chorus waves excited in the heart of the radiation belt during the ...

Topside Ionosphere and Plasmasphere Modelling Using GNSS Radio Occultation and POD Data

Remote Sensing, 2021
A 3D-model approach has been developed to describe the electron density of the topside ionosphere and plasmasphere based on Global Navigation Satellite System (GNSS) measurements onboard low Earth orbit satellites.

Quantifying hiss-driven energetic electron precipitation: A detailed conjunction event analysis [PDF]

, 2014
We analyze a conjunction event between the Van Allen Probes and the low-altitude Polar Orbiting Environmental Satellite (POES) to quantify hiss-driven energetic electron precipitation.
