Fig. 3From: Observing Earth’s magnetic environment with the GRACE-FO missionMagnetic residuals to CHAOS-7 (core, crustal, and large-scale magnetospheric field) in the three NEC (left) components and the field magnitude, F, (right) for GF1 and GF2, respectively. The panels in the third row show the difference between GF1 and GF2 residuals. The fourth panel shows the distribution of geomagnetic and solar activity indices and magnetic local timeBack to article page
