Simulations of Van Allen Probes Plasmaspheric Electron Density Observations [PDF]
Journal of Geophysical Research: Space Physics, 2018 AbstractWe simulate equatorial plasmaspheric electron densities using a physics‐based model (Cold PLasma, CPL; used in the ring current‐atmosphere interactions model) of the source and loss processes of refilling and erosion driven by empirical inputs.

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.

Penetration of magnetosonic waves into the plasmasphere observed by the Van Allen Probes [PDF]
Geophysical Research Letters, 2015 AbstractDuring the small storm on 14–15 April 2014, Van Allen Probe A measured a continuously distinct proton ring distribution and enhanced magnetosonic (MS) waves along its orbit outside the plasmapause. Inside the plasmasphere, strong MS waves were still present but the distinct proton ring distribution was falling steeply with distance.

Statistical Study on Spatial Distribution of Frequency‐Chirping ECH Elements by Van Allen Probes
Geophysical Research Letters, 2023 Electron cyclotron harmonic (ECH) waves can scatter electrons into the atmosphere causing diffuse aurora with diffusion coefficients depending on the wave frequency. Here we report the Van Allen Probe observations of chirping ECH elements, which are fine

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 ...

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 ...

Van Allen Probes Observations of a Three‐Dimensional Field Line Resonance at a Plasmaspheric Plume
Geophysical Research Letters, 2023 Field Line Resonances (FLRs) are a critical component in Earth's magnetospheric dynamics, associated with the transfer of energy between Ultra Low Frequency waves and local plasma populations. In this study we investigate how the polarisation of FLRs are

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.

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 ...
