Fig. 8

Temporal development of the sheet current densities and their differences for satellite Alpha and Bravo for the Northern Hemisphere in the period 11 to 31 March 2015. The top panel shows the integrated time series of the sheet current densities for satellite Alpha and Bravo for 300 orbits. The middle panel shows the sheet current densities of Swarm Alpha as a function of magnetic latitude and time (corresponding to middle plot of Fig. 5), and the bottom panel, the temporal development of their differences. Positive difference follows times with largest sheet current densities found by Swarm Alpha
