Fig. 6.From: The second generation of the GFZ Reference Internal Magnetic Model: GRIMM-2Comparison between GRIMM-2 and CHAOS-2: Left, power spectra of GRIMM-2 Static Core (SC) field, SV and SA at the Earth’s reference radius for 2005.0. The power spectra of the differences relative to CHAOS-2s are shown as doted lines. Right, the degree coherency between GRIMM-2 and CHAOS-2s is displayed.Back to article page
