Spatial Variation in the Responses of the Surface External and Induced Magnetic Field to the Solar Wind
R. M. Shore, M. P. Freeman, J. C. Coxon +3
We analyze the spatial variation in the response of the surface geomagnetic field (or the equivalent ionospheric current) to variations in the solar wind. Specifically, we regress…
Interplanetary Magnetic Field Control of PolarIonospheric Equivalent Current System Modes
R. M. Shore, M. P. Freeman, J. W. Gjerloev
We analyze the response of different ionospheric equivalent current modes to variations in the interplanetary magnetic field (IMF) components By and Bz. Each mode comprises a fixed…
Directed Network of Substorms Using SuperMAG Ground-Based Magnetometer Data
L. Orr, S. C. Chapman, J. W. Gjerloev
We quantify the spatiotemporal evolution of the substorm ionospheric current system utilizing the SuperMAG 100+ magnetometers.We construct dynamical directed networks from this dat…
Characterizing the ionospheric current pattern response to southward and northward IMF turnings with dynamical SuperMAG correlation networks
J. Dods, S. C. Chapman, J. W. Gjerloev
We characterize the response of the quiet time (no substorms or storms) large-scale ionospheric transient equivalent currents to north-south and south-north IMF turnings by using a…
A new technique for determining Substorm Onsets and Phases from Indices of the Electrojet (SOPHIE)
C. Forsyth, I. J. Rae, J. C. Coxon +4
We present a new quantitative technique that determines the times and durations of substorm expansion and recovery phases and possible growth phases based on percentiles of the rat…
Birkeland current effects on high-latitude groundmagnetic field perturbations
K. M. Laundal, S. E. Haaland, N. Lehtinen +8
Magnetic perturbations on ground at high latitudes are directly associated only with the divergence-free component of the height-integrated horizontal ionospheric current, $\textbf…
