Using neural networks to study the geomagnetic field evolution
Annals of Geophysics, 2008 study their time evolution in years. In order to find the best NN for the time predictions, we tested many different kinds of NN and different ways of their training, when the inputs and targets are long annual time series of synthetic ...

Modelling the effects of space weather at the Earth’s surface : a UK geoelectric field model [PDF]
, 2004 Geomagnetically Induced Currents (GIC), which can flow in technological systems such as power transmission grids, are a consequence of the geoelectric field induced at the surface of the Earth during geomagnetic storms.

Modeling of the Sq geomagnetic field induced by tidal oscillations of the atmosphere
Earth and Planetary PhysicsThe 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.
