Scientific paper

Geomagnetic disturbances produced by magnetospheric-ionospheric currents induce currents in ground technological networks that can cause operational problems for infrastructure such as power systems and pipelines. To assess the geomagnetic hazard to infrastructure a simulation package has been developed to calculate the geomagnetically induced currents (GIC) in these networks. The Simulator can start with either a specified ionospheric current such as the auroral electrojet or geomagnetic data from ground networks. Together with an Earth conductivity model these inputs are used to calculate the electric fields experienced by the ground network. The electric fields are then used as input to a network model to calculate the GIC. This talk describes the methodology of electric field calculations and network modelling. These simulations can be used to determine the GIC experienced during recorded large events or expected during high-risk scenarios and thereby contribute to assessing the risk from space weather disturbances.
