Simulated magnetopause losses and Van Allen Probe flux dropouts [PDF]

Geophysical Research Letters, 2014
AbstractThree radiation belt flux dropout events seen by the Relativistic Electron Proton Telescope soon after launch of the Van Allen Probes in 2012 (Baker et al., 2013a) have been simulated using the Lyon‐Fedder‐Mobarry MHD code coupled to the Rice Convection Model, driven by measured upstream solar wind parameters.

Wave-particle interactions in the outer radiation belts [PDF]

, 2015
Data from the Van Allen Probes have provided the first extensive evidence of non-linear (as opposed to quasi-linear) wave-particle interactions in space with the associated rapid (fraction of a bounce period) electron acceleration to hundreds of keV by ...

Magnetospheric Mass Density as Determined by ULF Wave Analysis

Frontiers in Astronomy and Space Sciences, 2021
The technique to estimate the mass density in the magnetosphere using the physical properties of observed magnetohydrodynamic waves is known as magnetoseismology.

Plasmatrough exohiss waves observed by Van Allen Probes: Evidence for leakage from plasmasphere and resonant scattering of radiation belt electrons [PDF]

, 2015
Exohiss waves are whistler mode hiss observed in the plasmatrough region. We present a case study of exohiss waves and the corresponding background plasma distributions observed by the Van Allen Probes in the dayside low-latitude region.

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.

Lightning Contribution to Overall Whistler Mode Wave Intensities in the Plasmasphere

Geophysical Research Letters, 2019
Electromagnetic waves generated by lightning propagate into the plasmasphere as dispersed whistlers. They can therefore influence the overall wave intensity in space, which, in turn, is important for dynamics of the Van Allen radiation belts.

Specifying High‐Altitude Electrons Using Low‐Altitude LEO Systems: The SHELLS Model

Space Weather, 2020
We describe an artificial neural network model of the near‐Earth space radiation environment. The geomagnetic activity index Kp and low‐earth‐orbit (LEO) electron flux measurements from the National Oceanic and Atmospheric Administration Polar‐orbiting ...

Global empirical models of plasmaspheric hiss using Van Allen Probes [PDF]

Journal of Geophysical Research: Space Physics, 2015
AbstractPlasmaspheric hiss is a whistler‐mode emission that permeates the Earth's plasmasphere and is a significant driver of energetic electron losses through cyclotron resonant pitch angle scattering. The Electric and Magnetic Field Instrument Suite and Integrated Science instrument on the Van Allen Probes mission provides vastly improved ...

Bayesian Inference of Quasi‐Linear Radial Diffusion Parameters using Van Allen Probes [PDF]

Journal of Geophysical Research: Space Physics, 2020
AbstractThe Van Allen radiation belts in the magnetosphere have been extensively studied using models based on radial diffusion theory, which is derived from a quasi‐linear approach with prescribed inner and outer boundary conditions. The 1D diffusion model requires the knowledge of a diffusion coefficient and an electron loss timescale, which is ...
