  "x_description": "This dataset contains quicklook plots of the electrostatic potential pattern representing ionospheric convection in the Northern Hemisphere measured by the SuperDARN radar network. Line-of-sight ionospheric velocity measurements from all of the radars over a two-minute interval are combined and a 6th order spherical harmonic fit is applied to the data, representing the global ionospheric potential during that two minute interval.  The data for each interval is displayed on a rectilinear 40x40 grid with 222 km spacing centred on the geomagnetic pole.  Noon is to the top of each panel, with dawn to the right.  The black contours are the ionospheric potential determined from the spherical harmonic fit to the velocity data. The location of the radar velocity measurements are shown by the coloured dots, with the colour corresponding to the velocity derived from the spherical harmonic fit.  The green line on each panel is the Heppner Maynard Boundary, encircling the lower edge of the SuperDARN velocity measurements.  The IMF clock angle from the OMNI data set is at the top right of each panel, with the cross polar cap potential (the difference between the maximum and the minimum in the potential pattern) shown in the lower right.  The quality flag for each map is also provided, with red being the lowest quality data, and green the highest quality.  The time at the top right of each panel corresponds to the start of the two-minute data interval.  Six maps are provided per hour, at ten minute cadence.",
