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 ...

Semiannual Variation in radiation belts particle fluxes: Van Allen probes observations [PDF]

, 2018
Abstract. The Semiannual Variation (SAV) is an annual pattern characterized by maxima around the equinoxes and minima near solstices observed in many space weather parameters. Several authors have studied this variation in the electron fluxes of the magnetosphere, focusing only in a few energy levels.

Explaining occurrences of auroral kilometric radiation in Van Allen radiation belts

Geophysical Research Letters, 2016
AbstractAuroral kilometric radiation (AKR) is a strong terrestrial radio emission and dominates at higher latitudes because of reflection in vicinities of the source cavity and plasmapause. Recently, Van Allen Probes have observed occurrences of AKR emission in the equatorial region of Earth's radiation belts but its origin still remains an open ...

Disappearance of plasmaspheric hiss following interplanetary shock [PDF]

, 2015
Plasmaspheric hiss is one of the important plasma waves controlling radiation belt dynamics. Its spatiotemporal distribution and generation mechanism are presently the object of active research.

Can We Intercalibrate Satellite Measurements by Means of Data Assimilation? An Attempt on LEO Satellites

Space Weather
Low Earth Orbit satellites offer extensive data of the radiation belt region, but utilizing these observations is challenging due to potential contamination and difficulty of intercalibration with spacecraft measurements at Highly Elliptic Orbit that can

Resonant scattering of energetic electrons by unusual low-frequency hiss [PDF]

, 2014
We quantify the resonant scattering effects of the unusual low-frequency dawnside plasmaspheric hiss observed on 30 September 2012 by the Van Allen Probes. In contrast to normal (∼100-2000 Hz) hiss emissions, this unusual hiss event contained most of its

Combining Van Allen Probes and CubeSat Observations to Estimate Storm‐Time Maximum Outer Radiation Belt Electron Fluxes

Space Weather
Understanding and forecasting extreme radiation belt electron fluxes has been a major goal in space weather since their discovery in 1958. In this study, by combining electron flux data from multiple satellite missions in different orbits, including Van ...
