Description:

The performance of the World Magnetic Model 2020 (WMM2020) was assessed by comparing its predictions on January 1, 2023 with that of a more recent model inferred from data collected by the European Space Agency (ESA) Swarm satellites from November 2013 until September 2022. For all magnetic field components, the WMM2020 global root-mean-square error increased by less than 5% over the past three years and remained well below the maximum error allowed by the U.S. Department of Defense WMM specification.
