Geophysical Research LettersElectrons in Earth's outer radiation belt are highly dynamic, with fluxes changing by up to orders of magnitude. The penetration of electrons from the outer belt to the inner belt is one such change observed during geomagnetic storms and was previously ...

Electron dropout echoes induced by interplanetary shock: Van Allen Probes observations
Geophysical Research Letters, 2016 On 23 November 2012, a sudden dropout of the relativistic electron flux was observed after an interplanetary shock arrival. The dropout peaks at ∼1 MeV and more than 80% of the electrons disappeared from the drift shell.

Evidence of Microbursts Observed Near the Equatorial Plane in the Outer Van Allen Radiation Belt
Geophysical Research Letters, 2018 We present the first evidence of electron microbursts observed near the equatorial plane in Earth's outer radiation belt. We observed the microbursts on 31 March 2017 with the Magnetic Electron Ion Spectrometer and Radiation Belt Storm Probes Ion ...

EMIC wave spatial and coherence scales as determined from multipoint Van Allen Probe measurements
Geophysical Research Letters, 2016 Electromagnetic ion cyclotron (EMIC) waves can provide a strong source of energetic electron pitch angle scattering. These waves are often quite localized, thus their spatial extent can have a large effect on their overall scattering efficiency.

Ion nose spectral structures observed by the Van Allen Probes
Journal of Geophysical Research: Space Physics, 2016 AbstractWe present a statistical study of nose‐like structures observed in energetic hydrogen, helium, and oxygen ions near the inner edge of the plasma sheet. Nose structures are spectral features named after the characteristic shapes of energy bands or gaps in the energy‐time spectrograms of in situ measured ion fluxes.
