Time series of AE index and the total polar current, I, for a period of 400 orbits (orbit number 7200 to 7799) from 7 March to 1 April 2015. The time series are smoothed with a 3-point running mean boxcar window for better comparison. The AE index is compared to the integrated time series of the sheet current densities for the Northern (top) and Southern (bottom) Hemisphere, respectively
