abstract: Declination is calculated using the current International Geomagnetic Reference Field (IGRF) model. Declination is calculated using the current World Magnetic Model (WMM) or International Geomagnetic Reference Field (IGRF) model. While results are typically accurate to 30 minutes of arc, users should be aware that several environmental factors can cause disturbances in the magnetic field.
purpose: The purpose of the calculators is to deliver trusted magnetic field values - past, present, and near future - to aid the public as well as the scientific community in proper navigation, positioning, and other operational and research magnetic field scenarios.
