Fig. 10From: Co-estimating geomagnetic field and calibration parameters: modeling Earth’s magnetic field with platform magnetometer dataGlobal maps of the radial SA up to degree 10 at the CMB for Model-B (left column), Model-A (center column), and the difference (right column). The maps are computed in 2009 (bottom row), 2013 (center row), and 2017 (top row). The projection is Equal Earth (Šavrič et al. 2018)Back to article page
