Figure 6From: Parent magnetic field models for the IGRF-12GFZ-candidatesPower spectra of the modelled magnetic fields. Power spectra of the magnetic field model and its SV, calculated for 2014.0 at the Earth’s surface. The spectra for the model presented in this paper - i.e. DCO(o) - for the GFZ-IGRF candidates and the power of the differences between the two models are also shown.Back to article page
