Summary
Abstract: The World Magnetic Model is the standard model of the US Department of Defense,
the UK Ministry of Defence, the North Atlantic Treaty Organization (NATO), and
the World Hydrographic Office (WHO) navigation and attitude/heading referencing
systems. It is also used widely in civilian navigation systems. The model,
associated software, and documentation are distributed by NGDC on behalf of

GEOSCIENTIFIC INFORMATION
Access Constraints This site provides access to the DoD software and current WMM model. The
software computes the main components of the geomagnetic field and their annual
changes. The programs are designed to be used in demand mode. The software is
available in both C and Fortran source code. The model file, wmm.cof, is
expected to reside in the same directory as the software. Note: The altitude is
referenced to the World Geodetic System 1984 (WGS 84) ellipsoid.
