Top Power spectra of the static field (n = 15–80, left) and of the linear SV (n = 1–15, right) from SIFMplus together with various reference and data-subset model at the Earth’s surface. Spectra of models are shown in dotted lines, spectra of differences between models in solid lines. Bottom Degree correlations of the SIFM and other models with respect to model MF7 (Maus 2010) for the static field (left) and with respect to CHAOS-6 (Finlay et al. 2016) for the linear SV (right)
