Geoelectric field maps of the UK from four large geomagnetic storms derived from thin-sheet model (NERC Grant NE/P017231/1)
This is a thin-sheet model of the regional geoelectric field covering the UK and Ireland, which is a combination of the response of the ground conductivity in a region with the spatial and temporal measurements of the rate of change of the horizontal components of the magnetic field.

The modelling code is based upon the work of Vasseur and Weidelt (1977) which has been employed in previous studies. The code computes the surface electric field arising at a particular period (for example, 120 s or 2 min) from a 2-D conductivity model of the surface and a layered subsurface. The geoelectric fields are made by inputting the average rate-of-change of the horizontal magnetic field for a fixed period as an input. We adopt the rate of change of the horizontal components of the field (dBX/dt and dBY /dt), using a difference of 2 minutes which matches the available magnetic time-series of minute-mean values. The output is the real and imaginary parts of the geoelectric field.
