Fig. 4.From: Space Weather opportunities from the Swarm mission including near real time applicationsRadial current density (red) derived from the lower orbiting pair of Swarm satellites A, B and the corresponding model input data (green) for the northern (np) and southern (sp) hemispheres (adapted from Ritter and Lühr, 2006). Electric current density is plotted over geomagnetic colatitude. (See online version for colored figures.)Back to article page
