Modelling the outer radiation belt as a complex system in a self-organised critical state [PDF]

open access: yesNonlinear Processes in Geophysics, 2005
The dynamic behaviour of the outer electron radiation belt makes this area of geo-space a candidate for the concept of self-organized criticality. It is shown here that frequency distributions of measured outer electron radiation belt data are well ...

Electron loss rates from the outer radiation belt caused by the filling of the outer plasmasphere: The calm before the storm [PDF]

open access: yes, 2009
Measurements from seven spacecraft in geosynchronous orbit are analyzed to determine the decay rate of the number density of the outer electron radiation belt prior to the onset of high-speed-stream-driven geomagnetic storms.

Magnetic field at geosynchronous orbit during high-speed stream-driven storms: Connections to the solar wind, the plasma sheet, and the outer electron radiation belt [PDF]

open access: yes, 2010
Superposed-epoch analysis is performed on magnetic field measurements from five GOES spacecraft in geosynchronous orbit during 63 high-speed stream-driven storms in 1995–2005. The field strength and the field stretching angle are examined as functions of

A density-temperature description of the outer electron radiation belt during geomagnetic storms [PDF]

open access: yes, 2010
Bi-Maxwellian fits are made to energetic-electron flux measurements from seven satellites in geosynchronous orbit, yielding a number density (n) and temperature (T) description of the outer electron radiation belt.

Reconstruction of the Radiation Belts for Solar Cycles 17–24 (1933–2017)

open access: yesSpace 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?

open access: yesGeophysical 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]

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 ...

Atmospheric losses of radiation belt electrons [PDF]

open access: yesJournal 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.

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/

Density and temperature of energetic electrons in the Earth's magnetotail derived from high-latitude GPS observations during the declining phase of the solar cycle [PDF]

open access: yes, 2011
Single relativistic-Maxwellian fits are made to high-latitude GPS-satellite observations of energetic electrons for the period January 2006-November 2010; a constellation of 12 GPS space vehicles provides the observations. The derived fit parameters (for
