Superfast precipitation of energetic electrons in the radiation belts of the Earth

open access: yesNature Communications, 2022
Energetic electron densities in the radiation belt increases during geomagnetic storms. Here, the authors show oblique whistler mode waves enhance electron losses and create strong fluxes of about 100 keV electrons precipitating into the atmosphere, that

New Perspective on Phase Space Density Analysis for Outer Radiation Belt Enhancements: The Influence of MeV Electron Injections

open access: yesGeophysical Research Letters, 2023
Observation of growing phase space density (PSD) peak in the outer electron radiation belt has been considered evidence for local wave‐driven acceleration as a primary cause of radiation belt enhancement.

Radiation Belts and Their Environment [PDF]

open access: yes, 2021
AbstractThe Van Allen radiation belts of high-energy electrons and ions, mostly protons, are embedded in the Earth’s inner magnetosphere where the geomagnetic field is close to that of a magnetic dipole. Understanding of the belts requires a thorough knowledge of the inner magnetosphere and its dynamics, the coupling of the solar wind to the ...

Constraining the Location of the Outer Boundary of Earth's Outer Radiation Belt

open access: yesEarth and Space Science, 2021
Characterizing the location of the outer boundary of the outer radiation belt is a key aspect of improving radiation belt models and helps to constrain our understanding of the mechanisms by which the source and seed electron populations are transported ...

Survey of ELF-VLF plasma waves in outer radiation belt observed by Cluster STAFF-SA experiment [PDF]

open access: yesAnnales Geophysicae, 2008
Various types of plasma waves have profound effects on acceleration and scattering of radiation belt particles. For the purposes of radiation belt modeling it is necessary to know statistical distributions of plasma wave parameters.

Large Igneous Province Record Through Time and Implications for Secular Environmental Changes and Geological Time‐Scale Boundaries

open access: yesGeophysical Monograph Series, Page 1-26., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Forecasting the Radiation Belts in Europe [PDF]

open access: yesSpace Weather, 2012
Weather forecasting has expanded to space weather. As of 1 March 2012, satellite operators and the general public will be able to obtain forecasts of the Earth’s radiation belts, thanks to the SPACECAST project. The opening of the first European system to forecast Earth’s radiation belts, part of the SPACECAST project, is funded by the European Union ...

Design considerations for the use of laser-plasma accelerators for advanced space radiation studies [PDF]

open access: yes, 2012
We present design considerations for the use of laser-plasma accelerators for mimicking space radiation and testing space-grade electronics. This novel application takes advantage of the inherent ability of laser-plasma accelerators to produce particle ...

Research advances in the data assimilative modeling of the Earth's radiation belt electrons

open access: yes地球与行星物理论评
The Earth's radiation belts are regions where high-energy charged particles congregate in near-Earth space. Given that high-energy particles in the radiation belts pose a severe threat to the safety of spacecraft in orbit and astronauts, it is of vital ...
