Enhanced Magnetic Model 2010

Metadata Updated: November 12, 2020

The Enhanced Magnetic Model (EMM) extends to degree and order 720, resolving magnetic anomalies down to 56 km wavelength. The higher resolution of the EMM results in significantly improved pointing accuracy than the World Magnetic Model (WMM), which uses spherical harmonic representation to degree and order 12, resolving the magnetic field at 3000 km wavelength. The EMM model provides the magnetic field vector at any desired location and altitude close to and above the Earth's surface.
