2 versions of the model are:

WMM2025: Standard model with a spatial resolution of 3 300 km (2 050 miles) at the equator.
WMMHR2025: A high-resolution model with an improved spatial resolution of approximately 300 km (186 miles), offering enhanced directional accuracy.

“We’re delighted to join with NOAA and BGS to publish WMM2025 and WMMHR2025, and we encourage users, where possible, to transition to the higher resolution model,” Mike Paniccia, a geodetic Earth scientist and the program manager for the World Magnetic Model (WMM) at the National Geospatial-Intelligence Agency (NGA), stated.
