Geomagnetic latitude, or magnetic latitude (MLAT), is a parameter analogous to
geographic latitude
In geography, latitude is a coordinate that specifies the north–south position of a point on the surface of the Earth or another celestial body. Latitude is given as an angle that ranges from –90° at the south pole to 90° at the north pol ...
, except that, instead of being defined relative to the
geographic poles, it is defined by the axis of the
geomagnetic dipole, which can be accurately extracted from the
International Geomagnetic Reference Field
The International Geomagnetic Reference Field (IGRF) is a standard mathematical description of the large-scale structure of the Earth's main magnetic field and its secular variation. It was created by fitting parameters of a mathematical model o ...
