Geomagnetic latitude is like the geographic latitude you are used to, but based on the Earth's magnetic pole instead of its rotational axis. Use this tool to find your geomagnetic latitude with a click on a map!
During a geomagnetic storm, the aurora will extend southward in geomagnetic latitude. The larger the GMD, the lower geomagnetic latitude!
Ground response models describe how a changing magnetic field relates to the induced electric field that creates the GIC hazard. These resources provide links to commonly-used ground response models.
