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