Quantifying extreme behaviour in geomagnetic activity [PDF]

, 2011
Understanding the extremes in geomagnetic activity is an important component in understanding just how severe conditions can become in the terrestrial space environment. Extreme activity also has consequences for technological systems.

What happens when the geomagnetic field reverses?

, 2012
During geomagnetic field reversals the radiation belt high-energy proton populations become depleted. Their energy spectra become softer, with the trapped particles of highest energies being lost first, and eventually recovering after a field reversal ...

WHUEMM: global core field modelling from multiple satellites and comparative evaluation of inversion strategy

Earth, Planets and Space
Measurements from low Earth orbit satellites play an important role in modern geomagnetic field modelling. In this study, we present two geomagnetic field models, WHUEMM-S, derived by sequential inversion, and WHUEMM-C, derived by comprehensive inversion.

Modeling of the Sq geomagnetic field induced by tidal oscillations of the atmosphere

Earth and Planetary Physics
The Sq (solar quiet) geomagnetic field is generated by the electric currents in the E-region of the ionosphere, driven by the atmospheric tides. It is a critical part of high-precision geomagnetic field modeling.
