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 ... -
Network community structure of substorms using SuperMAG magnetometers
Orr, L.; Chapman, S.C.; Gjerløv, Jesper; Guo, W. (Journal article; Peer reviewed, 2021)Geomagnetic substorms are a global magnetospheric reconfiguration, during which energy is abruptly transported to the ionosphere. Central to this are the auroral electrojets, large-scale ionospheric currents that are part ...
