World Magnetic Model 2025 Released | News | National Centers …
Dec 17, 2024 · The latest version of the World Magnetic Model (WMM), one of the key tools developed to model the change in Earth's magnetic field, has been released.The WMM is a spherical harmonic model of the Earth’s main magnetic field and its slow temporal change. The WMM is key to global navigation, ensuring that technological systems relying on the Earth’s magnetic field operate correctly.

World Magnetic Model 2025 - Catalog
The World Magnetic Model is the standard model used by the U.S. Department of Defense, the U.K. Ministry of Defence, the North Atlantic Treaty Organization (NATO) and the International Hydrographic Organization (IHO), for navigation, attitude and heading referencing systems using the geomagnetic field.
World Magnetic Model High Resolution (WMMHR)
The World Magnetic Model High Resolution (WMMHR) is an advanced geomagnetic field model that provides a more detailed, accurate depiction of the geomagnetic field than the World Magnetic Model (WMM). WMMHR2025 includes core field and secular variation coefficients for degrees n = 1 to 15.
