Fit of the CHAOS-7 model (red line) to secular variation data, annual differences of revised monthly means (black dots), at example ground observatories (three letter IAGA codes given). Also shown are the MCO_SHA_2Y model, version 0101 (Ropp et al. 2020) (green line), the CM6 model of Sabaka et al. (2020) (magenta line), and Model A of Alken et al. (2020) (cyan line)
