The Mag.num core field model as a parent for IGRF-13, and the recent evolution of the South Atlantic Anomaly
Abstract We present the GFZ candidate field models for the $$13{\mathrm{th}}$$ 13 th Generation International Geomagnetic Reference Field (IGRF-13). These candidates were derived from the Mag.num.IGRF13 geomagnetic core field model, which is constrained by Swarm satellite and ground observatory dat...
