First column: Target conductivity model filtered by spherical harmonics up to degree p = 5. Second column: Conductivity model recovered from noise-free data. Third column: Conductivity model recovered from data provided by the CI, using signals from all three satellites of the Swarm constellation and observatory measurements. Fourth column: Conductivity model recovered from data provided by the CI, using observatory measurements and signals from only those two satellites of the Swarm constellation that fly side-by-side (Swarm A and B). Note the different stratifications of target model and recovered model, especially in the overlap zone between 600 km and 800 km. Conductivities are in units of S/m.
