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 ...

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.

Van Allen Probes Observations of Oxygen Ions at the Geospace Plume

Frontiers in Astronomy and Space Sciences, 2021
The geospace plume couples the ionosphere, plasmasphere, and magnetosphere from sub-auroral regions to the magnetopause, on polar field lines, and into the magnetotail.

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.

A statistical study of the spatial distribution and source-region size of chorus waves using Van Allen Probes data [PDF]

Annales Geophysicae, 2018
The spatial distribution and source-region size of chorus waves are important parameters for understanding their generation. In this work, we analyze over 3 years of continuous wave burst-mode data from the Van Allen Probes mission and build a data ...

Van Allen Probes, THEMIS, GOES, and Cluster Observations of EMIC waves, ULF pulsations, and an electron flux dropout [PDF]

, 2016
We examined an electron flux dropout during the 12-14 November 2012 geomagnetic storm using observations from seven spacecraft: the two Van Allen Probes, Time History of Events and Macroscale Interactions during Substorms (THEMIS)-A (P5), Cluster 2, and ...

Energetic Proton Spectra Measured by the Van Allen Probes [PDF]

Journal of Geophysical Research: Space Physics, 2017
AbstractWe test the hypothesis that pitch angle scattering by electromagnetic ion cyclotron (EMIC) waves can limit ring current proton fluxes. For two chosen magnetic storms, during 17–20 March 2013 and 17–20 March 2015, we measure proton energy spectra in the region 3 ≤ L ≤ 6 using the RBSPICE‐B instrument on the Van Allen Probes.

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.
