				World Magnetic Model 2020


The World Magnetic Model 2020 (WMM2020) was released December 2019 and can be downloaded below. The file contains the necessary coefficients to upload into systems that require the update. A full report with more information about the WMM and this update will be published by NOAA's National Center for Environmental Information on their website in early 2020. The WMM is a joint product of the United States' National Geospatial-Intelligence Agency and the United Kingdom's Defence Geographic Centre developed jointly by the National Centers for Environmental Information and the British Geological Survey. The WMM is the standard model used by DoD, NATO, and IHO for a wide range of positional and navigation systems. WMM2020 is valid from December 10, 2019 through December 31, 2024. ​
