Fig. 6From: Local time and longitudinal variation of the ionospheric radial current: swarm observations and TIE–GCM simulationsLongitudinal variations of a northward component of magnetic field and c, d IRC in equinox under two different geomagnetic field configurations: IGRF and dipole cases. b MLT variations of IRC in IGRF and dipole cases in equinox. IRC is the longitudinal averaged value. Positive values in a represent the northward magnetic field. The solid and dotted lines represent IGRF and dipole resultsBack to article page
