{{Short description|Parameter defined by the axis of the geomagnetic dipole}}
'''Geomagnetic latitude''', or '''magnetic latitude''' ('''MLAT'''), is a parameter analogous to [geographic latitude](/source/latitude), except that, instead of being defined relative to the [geographic poles](/source/geographic_poles), it is defined by the axis of the [geomagnetic dipole](/source/dipole_model_of_the_Earth's_magnetic_field), which can be accurately extracted from the [International Geomagnetic Reference Field](/source/International_Geomagnetic_Reference_Field) (IGRF).<ref name="VanZandt">{{cite journal |last = VanZandt |first = T.
