AE, DST, and Their SuperMAG Counterparts: The Effect of Improved Spatial Resolution in Geomagnetic Indices
Bergin, A.; Chapman, S.C.; Gjerløv, Jesper (Journal article; Peer reviewed, 2020)For decades, geomagnetic indices have been used extensively to parameterize space weather events, as input to various models and as space weather specifications. The auroral electrojet (AE) index and disturbance storm time ... -
Extreme Event Statistics in Dst, SYM-H, and SMR Geomagnetic Indices
Bergin, A.; Chapman, Sandra; Watkins, N.W.; Moloney, N.R.; Gjerløv, Jesper (Journal article; Peer reviewed, 2023)Extreme space weather events are rare, and quantifying their likelihood is challenging, often relying on geomagnetic indices obtained from ground-based magnetometer observations that span multiple solar cycles. The Dst ...
