Figure 1From: Testing a toroidal magnetic field imaging method at the core-mantle boundary using a numerical dynamo modelSynthetic data from a dynamo model. (a, b) The radial component of the magnetic field B r at the CMB and (c, d) the core surface flow u H at r=0.984r o . Spatial resolution is truncated at spherical harmonic degree 12 in (b) and (d).Back to article page
