Fig. 11From: An electric circuit model of the Earth’s polar electrojets and field-aligned currents for the estimation of magnetospheric magnetic field from along-track Swarm magnetic dataThe same as Fig. 9, but for the mid-latitude residuals \(({\varvec{d}}-{\varvec{G}}\hat{{\varvec{m}}})_{\mathrm{ML}}\). The common value of \(\alpha ^2\) used for the analysis all Swarm data was chosen equal to \(\alpha ^2=3\times 10^{-15}\) nT\(^2\)A\(^{-2}\) (large circles)Back to article page
