(upper left) Locations for the Swarm A (blue), Swarm B (green), Swarm C (red), and SuperDARN (black) data sets. SuperDARN data locations are for January 20, 2001 11:20–11:24 UT. Convection velocity (colored scale) calculated from (upper right) SuperDARN, (lower left) SuperDARN and Swarm C, and (lower right) SuperDARN and Swarm A, and C measurements. Contours of electric potential are plotted with a 6 kV contour spacing. The plus and cross indicate the maximum and minimum potential and the cross polar cap potential is indicated where it could be determined, here on the lower left panel, where ground and Swarm A and C data have been combined (from Fioria et al., 2013).
