Scaling laws for the inner structure of the radiation belts

open access: yesGeophysical Research Letters, 2017
Accurately modeling the evolution of the electron radiation belts within the plasmasphere represents both an imperative goal for space weather forecasting and a great challenge.

Dynamics of Radiation Belt Particles [PDF]

open access: yesSpace Science Reviews, 2012
This paper reviews basic concepts of particle dynamics underlying theoretical aspect of radiation belt modeling and data analysis. We outline the theory of adiabatic invariants of quasiperiodic Hamiltonian systems and derive the invariants of particle motion trapped in the radiation belts.

Quantitative assessment of Earth’s radiation belt modeling [PDF]

open access: yes, 2017
The “Quantitative Assessment of Radiation Belt Modeling” focus group was in place at Geospace Environment Modeling from 2014 to 2018. The overarching goals of this focus group were to bring together the current state‐of‐the‐art models for the ...

UBER v1.0: a universal kinetic equation solver for radiation belts [PDF]

open access: yesGeoscientific Model Development, 2021
Recent proceedings in radiation belt studies have proposed new requirements for numerical methods to solve the kinetic equations involved. In this article, we present a numerical solver that can solve the general form of the radiation belt Fokker–Planck ...

Chorus wave-normal statistics in the Earth's radiation belts from ray tracing technique [PDF]

open access: yesAnnales Geophysicae, 2012
Discrete ELF/VLF (Extremely Low Frequency/Very Low Frequency) chorus emissions are one of the most intense electromagnetic plasma waves observed in radiation belts and in the outer terrestrial magnetosphere.

Discovery of a transient radiation belt at Saturn [PDF]

open access: yes, 2008
Radiation belts have been detected in situ at five planets. Only at Earth however has any variability in their intensity been heretofore observed, in indirect response to solar eruptions and high altitude nuclear explosions. The Cassini spacecraft's MIMI/

Differentiating Between the Leading Processes for Electron Radiation Belt Acceleration

open access: yesFrontiers in Astronomy and Space Sciences, 2022
Many spacecraft fly within or through a natural and variable particle accelerator powered by the coupling between the magnetosphere and the solar wind: the Earth’s radiation belts.

A model of the secondary radiation belt [PDF]

open access: yesJournal of Geophysical Research: Space Physics, 2008
Products of nuclear reactions between primary radiation belt protons and constituents of the tenuous upper atmosphere form a collocated secondary radiation belt. A calculation of the time‐dependent secondary intensity provides a model specification of this environmental component for low‐ and medium‐altitude satellite orbits.

Radiation belt electron scattering by whistler-mode chorus in the Jovian magnetosphere: Importance of ambient and wave parameters

open access: yesEarth and Planetary Physics, 2018
Whistler-mode chorus waves are regarded as an important acceleration mechanism contributing to the formation of relativistic and ultra-relativistic electrons in the Jovian radiation belts.

Dependence of Energetic Electron Precipitation on the Geomagnetic Index Kp and Electron Energy [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2013
It has long been known that the magnetospheric particles can precipitate into the atmosphere of the Earth. In this paper we examine such precipitation of energetic electrons using the data obtained from low-altitude polar orbiting satellite ...
