Abstract The Van Allen Probes Electric Fields and Waves (EFW) instrument provided
measurements of electric fields and spacecraft floating potentials over a wide dynamic range …

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 …

We investigate the outer radiation belt electron energy spectra of the highest fluxes
observed during storms based on Van Allen Probes measurements, which demonstrate a …

Observational studies of the Earth's radiation belts indicate that Alfvénic fluctuations in the
frequency range of 2–25 mHz accelerate electrons to relativistic energies. For decades …

Quasilinear theories have been shown to well describe a range of transport phenomena in
magnetospheric, space, astrophysical and laboratory plasma “weak turbulence” scenarios. It …

Geospace disturbances refer collectively to the variations of the geomagnetic field and the
trapped particle populations in the near-Earth space. These are the result of transient and …

Abstract The fast Van Allen radiation belt electron dynamics during geomagnetic storms
have not yet been fully explained, in part due to limitations of standard satellite missions in …

Earth's radiation belts are extremely important for space weather because they can store
and accelerate particles to relativistic energies, which can have a potential impact on …

Abstract Field Line Resonances (FLRs) are a critical component in Earth's magnetospheric
dynamics, associated with the transfer of energy between Ultra Low Frequency waves and …

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 …
