Note:
Because WMM is a "predictive only" model, we do not make the older models (WMM.COF files) widely available.
We recommend to make use of the International Geomagnetic Reference Field ( IGRF)
models for years prior to 2015. IGRF is updated retrospectively to provide the best available estimate of the
geomagnetic field back to 1900.
