Figure 5From: Stochastic forecasting of the geomagnetic field from the COV-OBS.x1 geomagnetic field model, and candidate models for IGRF-12Example of COV-OBS.x1 MF (right) and SV (left) coefficient series (blue) and comparison with CHAOS4plus_v4 (red). From top to bottom: \({g_{1}^{0}}\), \({g_{2}^{1}}\), and \({g_{8}^{1}}\). Error bars indicate ± one standard deviation of the COV-OBS.x1 model errors.Back to article page
