Lightning-induced relativistic electron precipitation from the inner radiation belt [PDF]
Nature CommunicationsThe Earth’s radiation belts are maintained by a number of acceleration, loss and transport mechanisms, and the electron fluxes at any given time are highly variable.

Processes in auroral oval and outer electron radiation belt [PDF]
Earth, Planets and Space, 2018 We have analyzed the role of auroral processes in the formation of the outer radiation belt, considering that the main part of the auroral oval maps to the outer part of the ring current, instead of the plasma sheet as is commonly postulated.

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.

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

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.
