Comparison between SuperDARN and Swarm constellation measurements. Mean ionospheric plasma convection maps in the high-latitude region obtained using SuperDARN data. Colour indicates electrostatic potential according to the colour scale at the bottom. Superposed to the mean ionospheric plasma convection maps the values of the Hurst exponent along the trajectories of the Swarm satellites. a–f Different time intervals as reported at the top of each panel. The coordinates are AACGM latitude, from \(60^{\circ }\)N to the north pole, and the magnetic local time (MLT), with the local noon at the top and local midnight at the bottom. Concentric circles are magnetic parallels drown at \(10^{\circ }\)
