Fig. 4From: Regional geomagnetic core field and secular variation model over the Iberian Peninsula from 2014 to 2020 based on the R-SCHA techniqueR-SCHA core magnetic field components: a X, b Y, c Z and d intensity (colormaps) and its secular variation (blue lines) in nT/yr in 2020.0 calculated at surface height. The dashed white line of b indicates the null east component (Y) line, i.e. the agonic lineBack to article page
