GIC: ground conductivity


This demo shows the effect of the ground conductivity on GIC. The left-hand-side plot shows the modelled GIC on October 29, 2003, on 06-07 UT assuming the conductivity model of West Finland to be valid everywhere.

The right-hand-side plot shows the difference from this case, when the full conductivity model is used. The full model has smaller conductivities in East and North Finland, which leads to larger electric fields and GIC there. In West Finland, GIC remains nearly equal to the case of the single ground model.
