Reproduction of substorm auroral currents in the ionosphere using a machine-learning-based emulator and SuperDARN data assimilation

Auroral electrojet dynamics during isolated substorms are reproduced using a machine-learning-based emulator with SuperDARN data assimilation. Representing such short-timescale variability is important for improving space-weather prediction relevant to technological systems. Reproducing this variability remains challen...
