Drift phase resolved diffusive radiation belt model: 1. Theoretical framework
Frontiers in Astronomy and Space Sciences, 2023 Most physics-based models provide a coarse three-dimensional representation of radiation belt dynamics at low time resolution, of the order of a few drift periods. The description of the effect of trapped particle transport on radiation belt intensity is

A data assimilation-based forecast model of outer radiation belt electron fluxes
Earth and Planetary Physics, 2023 Because radiation belt electrons can pose a potential threat to the safety of satellites orbiting in space, it is of great importance to develop a reliable model that can predict the highly dynamic variations in outer radiation belt electron fluxes.

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 ...

The Astrophysical Journal, 2009 The magnetic field of the solar corona has a large-scale dipole character, which maps into the bipolar field in the solar wind. Using standard representations of the coronal field, we show that high-energy ions can be trapped stably in these large-scale closed fields.

Differentiating Between the Leading Processes for Electron Radiation Belt Acceleration
Frontiers 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.

Reconstruction of the Radiation Belts for Solar Cycles 17–24 (1933–2017)
Space Weather, 2021 We present a reconstruction of the dynamics of the radiation belts from solar cycles 17 to 24 which allows us to study how radiation belt activity has varied between the different solar cycles.

Does Uranus' Asymmetric Magnetic Field Produce a Relatively Weak Proton Radiation Belt?
Geophysical Research Letters, 2022 Since the Voyager 2 flyby in 1986 the radiation belts of Uranus have presented a problem for physicists. The observations indicate the electron radiation belt is far more intense than the proton radiation belt, and while the electron intensities are ...

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

Atmospheric losses of radiation belt electrons [PDF]
Journal of Geophysical Research: Space Physics, 2003 A numerical model of the low‐altitude energetic electron radiation belt, including the effects of pitch angle diffusion into the atmosphere and azimuthal drift, predicts lifetimes and longitude‐dependent loss rates as a function of electron energy and diffusion coefficient.
