Earth's core magnetic field model Mag.num and the IGRF 13 candidate
, 2020 <p>The Earth's core magnetic field model Mag.num was the parent model for the GFZ IGRF 13 candidate submission. The model is based on geomagnetic ground observatory and Swarm satellite observations. Epochs 2020.0 and beyond were not covered by the data available at the time of submission and our results were based on predictions.

Local gravity network as a reference station for the IGRF
, 2019 The newly created International Gravity Reference Frame (IGRF) will heavily rely on widely distributed reference stations. It is required that at any time of the year the instantaneous value of gravity will be available at such reference stations.
