    Predictability of Geomagnetically Induced Currents as a Function of Available Magnetic Field Information by Matthew A. Grawe, Jonathan J. Makela

    Published 2021-08-01
    “…Abstract Prediction of geomagnetically induced currents (GICs) plays a critical role in the gestalt of space weather forecasting and risk assessment, giving power companies time to enact mitigation strategies that could avoid a catastrophic collapse of the power grid caused by, for example, the impact of an Earth‐directed coronal mass ejection. Sun‐to‐mud prediction of the surface magnetic field (and/or its time derivative) is a long‐standing goal for both first‐principles and data‐driven models. …”
