Fig. 5From: COV-OBS.x2: 180 years of geomagnetic field evolution from ground-based and satellite observationsMF (left) and SV (right) time series of \(g_1^0\) (top), \(g_7^4\) (middle) and \(g_{12}^{4}\) (bottom) for COV-OBS.x2 (black), compared with CHAOS-7 (orange) between 1998 and 2020. The gray-shaded areas represent the \(\pm \sigma \) dispersion within the ensemble of COV-OBS.x2 modelsBack to article page
