Fig. 8From: A secular variation candidate model for IGRF-13 based on Swarm data and ensemble inverse geodynamo modellingHuber weights attributed to IPGP’s candidate. Top left: their distribution for the three components of the secular variation taken together (note that the y-scale is logarithmic). Top right: their spatial distribution for the vertical component of the secular variation. Bottom left: same for the North–South component. Bottom right: same for the East–West component.
