Simulations of the 2003 Halloween Storms and their generated GICs using RAM-SCBE and the SWMF.

Large scale geomagnetic storms pose a threat to both our space based and ground based infrastructure. Current work is being done to access the effects of extremely large storm events on the power grid. In order to properly analyze the impact of these events it is necessary to construct robust and accurate simulations of the magnetospheric space in order to drive models of geomagnetically induced currents (GICs). Accurately simulating these large scale events is a continuing challenge to the magnetosphere community. Recent advancements and continuing enhancements of the RAM-SCBE model, as well as its integration into the SWMF, have allowed us expand our capabilities to include the simulation and modeling of some of the most extreme events. Here we present simulations of two of the largest storms during the space age, their effects on the magnetospheric environment, and the GICs generated during these storm times.
