Fig. 9From: Probing 3-D electrical conductivity of the mantle using 6 years of Swarm, CryoSat-2 and observatory magnetic data and exploiting matrix Q-responses approachEstimated 3-D conductivity model. Conductivities are shown as \(\log _{10}\frac{\sigma _{\text {3D}}}{\sigma _{\text {1D}}}\) where \(\sigma _{\text {1D}}\) stands for the 1-D background conductivityBack to article page
