Fig. 10From: Statistical analysis of geomagnetic field intensity differences between ASM and VFM instruments onboard Swarm constellationEmpirical mode decomposition of \(T_{\mathrm{EU}}\). From top to bottom \(T_{\mathrm{EU}}\) of the VFM onboard Swarm B; IMF\(_k\) for \(k = 1, \ldots , 13\) and the residue resulting from EMD applied to \(T_{\mathrm{EU}}\). The characteristic timescale increases with the IMF number k Back to article page
