Effect of ICME-Driven Storms on Field-Aligned and Ionospheric Currents From AMPERE and SuperMAG
Pedersen, M.N.; Vanhamäki, H.; Aikio, A.T.; Waters, C.L.; Gjerløv, Jesper; Käki, S.; Workayehu, A.B. (Journal article; Peer reviewed, 2022)This study investigates the field-aligned currents (FACs) and ionospheric equivalent currents for interplanetary coronal mass ejection (ICME)-driven storms by considering 45 events with a minimum Dst ≤ −50 nT. The FACs and ... -
Field-Aligned and Ionospheric Currents by AMPERE and SuperMAG During HSS/SIR-Driven Storms
Pedersen, M.N.; Vanhamäki, H.; Aikio, A.T.; Käki, S.; Workayehu, A.B.; Waters, C.L.; Gjerløv, Jesper (Journal article; Peer reviewed, 2021)This study considers 28 geomagnetic storms with Dst $\leq-50$ nT driven by high-speed streams (HSSs) and associated stream interaction regions (SIRs) during 2010-2017. Their impact on ionospheric horizontal and field-aligned ...
