Fig. 7From: A secular variation candidate model for IGRF-13 based on Swarm data and ensemble inverse geodynamo modellingDistribution of proposed rates of change for some Gauss coefficients of degrees 1 and 2 against the statistics of the COV-OBS.x1 geomagnetic field model (Gillet et al. 2015) and the Coupled Earth dynamo model (Aubert et al. 2013). The grey dashed lines correspond to the rates of change proposed by the 13 other SV candidates to IGRF-13Back to article page
