Modeling inward diffusion and slow decay of energetic electrons in the Earth\u27s outer radiation belt [PDF]

, 2015
A new 3-D diffusion code is used to investigate the inward intrusion and slow decay of energetic radiation belt electrons (\u3e0.5 MeV) observed by the Van Allen Probes during a 10 day quiet period on March 2013.

Bayesian Model for HOPE Mass Spectrometers on Van Allen Probes [PDF]

Journal of Geophysical Research: Space Physics, 2020
Abstract Space instruments rely heavily on modeling to predict and understand the instrument response, enabling a determination of the capabilities and resolution. The Bayesian approach provides a framework to incorporate prior knowledge and propagate uncertainty to predict the instrument response.

Formation of the oxygen torus in the inner magnetosphere: Van Allen Probes observations [PDF]

, 2015
We study the formation process of an oxygen torus during the 12–15 November 2012 magnetic storm, using the magnetic field and plasma wave data obtained by Van Allen Probes.

Statistical characteristics of EMIC waves: Van Allen Probe observations [PDF]

Journal of Geophysical Research: Space Physics, 2015
AbstractUtilizing the data from the magnetometer instrument which is a part of the Electric and Magnetic Field Instrument Suite and Integrated Science instrument suite on board the Van Allen Probe A from September 2012 to April 2014, when the apogee of the satellite has passed all the magnetic local time (MLT) sectors, we obtain the statistical ...

Developing Chorus Wave Model Using Van Allen Probe and Arase Data

Proceedings of the XXXVth URSI General Assembly and Scientific Symposium – GASS 2023, 2023
Chorus waves play an important role in the dynamic evolution of energetic electrons in the Earth’s radiation belts and ring current. Due to the orbit limitation of Van Allen Probes, our previous chorus wave model developed using Van Allen Probe data is limited to low latitude.

Outer radiation belt and inner magnetospheric response to sheath regions of coronal mass ejections: a statistical analysis [PDF]

Annales Geophysicae, 2020
The energetic electron content in the Van Allen radiation belts surrounding the Earth can vary dramatically at several timescales, and these strong electron fluxes present a hazard for spacecraft traversing the belts.

Competing source and loss mechanisms due to wave-particle interactions in Earth’s outer radiation belt during the 30 September to 3 October 2012 geomagnetic storm [PDF]

, 2014
Drastic variations of Earth’s outer radiation belt electrons ultimately result from various competing source, loss, and transport processes, to which wave-particle interactions are critically important.

An Empirical Model of the Equatorial Electron Pitch Angle Distributions in Earth's Outer Radiation Belt

Space Weather, 2022
In this study, we present an empirical model of the equatorial electron pitch angle distributions (PADs) in the outer radiation belt based on the full data set collected by the Magnetic Electron Ion Spectrometer (MagEIS) instrument onboard the Van Allen ...

Evidence of stronger pitch angle scattering loss caused by oblique whistler-mode waves as compared with quasi-parallel waves [PDF]

, 2014
International audienceWave normal distributions of lower-band whistler-mode waves observed outside the plasmapause exhibit two peaks: one near the parallel direction and the other at very oblique angles.
