Intense chorus waves are the cause of flux-limiting in the heart of the outer radiation belt [PDF]

Scientific Reports, 2022
Chorus waves play a key role in outer Van Allen electron belt dynamics through cyclotron resonance. Here, we use Van Allen Probes data to reveal a new and distinct population of intense chorus waves excited in the heart of the radiation belt during the ...

Wave–particle interaction effects in the Van Allen belts [PDF]

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).

Quantifying the Size and Duration of a Microburst‐Producing Chorus Region on 5 December 2017 [PDF]

Geophysical Research Letters, 2022
Microbursts are impulsive (30 keV) precipitation (FIREBIRD II and AC6 CubeSats, POES) to determine the size of the microburst‐producing chorus source region beginning on 5 December 2017.

Competing mechanisms of radial and local diffusion in radiation belt electron dynamics during quiet-geomagnetic conditions [PDF]

Scientific Reports
While previous investigations utilizing high-resolution satellite observations (e.g., Van Allen Probes) have elucidated the competition between radial diffusion and local wave-driven acceleration mechanisms during geomagnetic storms, the relative ...

Wave-induced loss of ultra-relativistic electrons in the Van Allen radiation belts. [PDF]

Nature Communications, 2016
The dipole configuration of the Earth's magnetic field allows for the trapping of highly energetic particles, which form the radiation belts. Although significant advances have been made in understanding the acceleration mechanisms in the radiation belts,

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 ...

Enhanced Radiation Levels at Aviation Altitudes and Their Relationship to Plasma Waves in the Inner Magnetosphere

Space Weather, 2023
It is believed that galactic cosmic rays and solar energetic particles are the two major sources of ionizing radiation. However, the radiation source may also be due to relativistic electrons that are associated with precipitation from the Van Allen ...
