Three principal components describe the spatiotemporal development of mesoscale ionospheric equivalent currents around substorm onsets

<p>Substorms are a commonly occurring but insufficiently understood form of dynamics in the coupled magnetosphere–ionosphere system, associated with space weather disturbances and auroras. We have used principal component analysis (PCA) to characterize the spatiotemporal development of ionosph...
