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 2010. IGRF is updated retrospectively to provide the best available estimate of the geomagnetic field back to 1900.
