Fig. 5From: Sequential modelling of the Earth’s core magnetic fieldTimes series for SV Gauss coefficients of degrees 1, 3, 5 and order 0. The times series span 2000 to 2019.75. The dotted blue lines represent the Chaos-6-×9 model. The orange line represents the MCM model before the smoothing operation. The green line represents the final model, after smoothing. Both series are presented within a \(2\sigma\) interval. Top: CE series. Bottom: HS seriesBack to article page
