  "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. The line-of-sight ionospheric velocity measurements from all of the radars over a 2-minute interval are combined and a 6th order spherical harmonic fit is applied to the data. This 6th order spherical harmonic fit represents the ionospheric potential and is displayed in the top panels as a coloured contour. The data are provided in a magnetic local time/magnetic latitude coordinate system with noon at the top and dusk to the left.  The plots are provided a ten minute cadence, each plot contains two minutes of radar data.  The colour scale for the ionospheric potential is provided at the bottom of the page.  Below is the cross polar cap potential (CPCP) data for the day, defined as the difference between the maximum and minimum of the 6th order potential fit, as an indication of the strength of the convection over the 24 hour period. The number of individual radar data points that went into each map is also provided, in the lower panel. The solid line represents the threshold of 200 data points associated with the quality flag.",
