Simulation of Van Allen Probes plasmapause encounters [PDF]

Journal of Geophysical Research: Space Physics, 2014
AbstractWe use anE×B‐driven plasmapause test particle (PTP) simulation to provide global contextual information for in situ measurements by the Van Allen Probes (Radiation Belt Storm Probes (RBSP)) during 15–20 January 2013. During 120 h of simulation time beginning on 15 January, geomagnetic activity produced three plumes.

Wave–particle interaction effects in the Van Allen belts

Earth, Planets and Space, 2021
Discovering such structures as the third radiation belt (or “storage ring”) has been a major observational achievement of the NASA Radiation Belt Storm Probes program (renamed the “Van Allen Probes” mission in November 2012).

Inter‐Calibrated Measurements of Intense Whistlers by Arase and Van Allen Probes [PDF]

Journal of Geophysical Research: Space Physics, 2021
AbstractMeasurements of electromagnetic waves in space plasmas are an important tool for our understanding of physical processes in this environment. Inter‐calibration of data from different spacecraft missions is necessary for combining their measurements in empirical models or case studies.

A Tale of Two Radiation Belts: The Energy‐Dependence of Self‐Limiting Electron Space Radiation

Geophysical Research Letters, 2021
The flux of energetic electrons in the terrestrial Van Allen Belts varies by orders of magnitude during a magnetic storm. Here, we show how the dynamics of these electrons are clearly separated by energy into two distinct populations which are governed ...

Initial measurements of O-ion and He-ion decay rates observed from the Van Allen probes RBSPICE instrument. [PDF]

J Geophys Res Space Phys, 2014
H-ion (∼45 keV to ∼600 keV), He-ion (∼65 keV to ∼520 keV), and O-ion (∼140 keV to ∼1130 keV) integral flux measurements, from the Radiation Belt Storm Probe Ion Composition Experiment (RBSPICE) instrument aboard the Van Allan Probes spacecraft B, are ...

Statistics and Empirical Models of the Plasmasphere Boundaries From the Van Allen Probes for Radiation Belt Physics

Geophysical Research Letters, 2022
We deduce the electron plasma density from the NASA Van Allen Probes Electric Field and Waves and Electric and Magnetic Field Instrument Suite and Integrated Science measurements and extract the plasmasphere boundaries throughout 2012–2019.

Dynamics of the inner electron radiation belt: A review

Earth and Planetary Physics, 2023
The Van Allen radiation belts are an extraordinary science discovery in the Earth magnetosphere and consist of two electron belts. The inner Van Allen belt contains electrons of 10s to 100s keV; the outer belt consists mainly of 0.1−10 MeV electrons ...

Simulated Trapping of Solar Energetic Protons for the 8–10 March 2012 Geomagnetic Storm: Impact on Inner Zone Protons as Measured by Van Allen Probes

Journal of Geophysical Research: Space Physics, 2023
Solar energetic protons (SEPs) have been shown to contribute significantly to the inner zone trapped proton population for energies 1.3 (Selesnick et al., 2007, https://doi.org/10.1029/2006sw000275).

An empirical model of the global distribution of plasmaspheric hiss based on Van Allen Probes EMFISIS measurements

Earth and Planetary Physics, 2020
Using wave measurements from the EMFISIS instrument onboard Van Allen Probes, we investigate statistically the spatial distributions of the intensity of plasmaspheric hiss waves.

Oxygen Ion Dynamics in the Earth's Ring Current: Van Allen Probes Observations [PDF]

, 2019
Oxygen (O+) enhancements in the inner magnetosphere are often observed during geomagnetically active times, such as geomagnetic storms. In this study, we quantitatively examine the difference in ring current dynamics with and without a substantial O+ ion
