Description

Auroral Kilometric Radiation (AKR) is a strong Earth-based radio emission generated by the acceleration of electrons along auroral latitude magnetic field lines. AKR is closely linked to auroral ionospheric activity, with greater irradiance correlating with stronger auroral electrojets and enhanced particle precipitation. AKR provides a means to remotely sense ionosphere-magnetosphere coupling, which becomes most dynamic during magnetospheric substorms. These substorms exhibit clear onset signatures in auroral imagery and ground-based magnetometer data. Using these signatures and an AKR burst list identified from Wind/WAVES observations, we investigate the properties of AKR that indicate substorm occurrence, contributing to a greater understanding of ionosphere-magnetosphere dynamics throughout the substorm timeline.
