Earth’s northern magnetic pole is moving quickly away from the Canadian Arctic toward Siberia.
A new and updated version of the World Magnetic Model (WMM) is released every five years. This movement has forced NCEI’s scientists to update the WMM mid-cycle. With the last release in 2015, the next version is scheduled for release at the end of 2019.

Due to unplanned variations in the Arctic region, scientists have released a new model to more accurately represent the change of the magnetic field between 2015 and now.

This out-of-cycle update before next year’s official release of WMM2020 will ensure safe navigation for military applications, commercial airlines, search and rescue operations, and others operating around the North Pole.
