Fig. 6From: Statistical analysis of geomagnetic field intensity differences between ASM and VFM instruments onboard Swarm constellationVariance and comparison among \(\Delta F_{\mathrm{P}}\) and different reconstructed signals. a Variance associated with each IMF k obtained decomposing \(\Delta F_{\mathrm{P}}\) plotted as a function of the associated mean frequency \(< f_k>\). Colors used in the case of the variance of each IMF correspond to those used in Fig. 4. b A zoom showing a comparison among the original signal \(\Delta F_{\mathrm{P}}\) and the different signals reconstructed using Eqs. (3), (4) and (5), respectively. Data here considered are relative to Swarm A.Back to article page
