DIFI-4 IONOSPHERE MAGNETIC FIELD MODEL

At mid- and low-latitudes and during quiet geomagnetic times, electrical currents flowing in the ionosphere generate magnetic variations of a few tens of nT on the ground and at low-Earth orbit altitudes. The Sq ("solar quiet") current system takes the form of two large-scale vortices on the dayside of the Earth, one in each hemisphere. Due to a local enhancement of conductivity, a stronger current, the equatorial electrojet (EEJ), flows along the dip equator and generates magnetic signatures that can reach up to 150 nT at some locations.
