Fig. 10

Time-dependence of example spherical harmonic coefficients of the internal field SV from CHAOS-7 (solid red line). Also shown are the CM6 model of Sabaka et al. (2020) (magenta line), MCO_SHA_2Y, a preliminary model derived following the approach of Ropp et al. (2020) (green line) and model A of Alken et al. (2020) (cyan line). Top two rows are zonal coefficients, bottom two rows are sectoral coefficients, middle two rows are tesseral coefficients
