An inversion framework was applied for the non-dipole part of the geomagnetic core field model CHAOS-6 using data from three different satellite missions and ground observatories. This framework uses a forward model of stationary helical current systems, based on geodynamo simulations of low viscosity, to invert for. Here the authors present the geographical distribution of the resulting current systems and it’s comparison with the properties of core surface flows inverted by other research groups. The full spatial structure of the inverted current densities is revealed as well. |
