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.

Quasi Thermal Noise Spectroscopy for Van Allen Probes [PDF]
Journal of Geophysical Research: Space Physics, 2019 AbstractQuasi thermal fluctuations in the Langmuir/upper‐hybrid frequency range are pervasively observed in space plasmas including the radiation belt and the ring current region of inner magnetosphere as well as the solar wind. The quasi thermal noise spectroscopy may be employed in order to determine the electron density and temperature as well as to

Analytical Chorus Wave Model Derived from Van Allen Probe Observations [PDF]
Journal of Geophysical Research: Space Physics, 2019 AbstractChorus waves play an important role in the dynamic evolution of energetic electrons in the Earth's radiation belts and ring current. Using more than 5 years of Van Allen Probe data, we developed a new analytical model for upper‐band chorus (UBC; 0.5fce < f < fce) and lower‐band chorus (LBC; 0.05fce < f < 0.5fce) waves, where fce is ...

A statistical analysis of the Kappa-type energy spectrum distribution of radiation belt electrons observed by Van Allen Probes [PDF]
Earth and Planetary Physics, 2023 The energy spectrum of energetic electrons is a key factor representing the dynamic variations of Earth’s Van Allen radiation belts. Increased measurements have indicated that the commonly used Maxwellian and Kappa distributions are inadequate for ...

Spacecraft surface charging within geosynchronous orbit observed by the Van Allen Probes. [PDF]
Space Weather, 2016 AbstractUsing the Helium Oxygen Proton Electron (HOPE) and Electric Field and Waves (EFW) instruments from the Van Allen Probes, we explored the relationship between electron energy fluxes in the eV and keV ranges and spacecraft surface charging. We present statistical results on spacecraft charging within geosynchronous orbit by L and MLT.

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.

Excitation of nightside magnetosonic waves observedby Van Allen Probes [PDF]
Journal of Geophysical Research: Space Physics, 2014 During the recovery phase of the geomagnetic storm on 30-31 March 2013, Van Allen Probe A detected enhanced magnetosonic (MS) waves in a broad range of L = 1.8-4.7 and magnetic local time (MLT) = 17-22 h, with a frequency range ∼10-100 Hz.
