Ionospheric vorticity across the northern polar ionosphere determined from SuperDARN velocity data - 2000 to 2005 inclusive

The data set comprises of ionospheric vorticity estimates determined from measurements of ionospheric velocity made by the Super Dual Auroral Radar Network (SuperDARN). The vorticity estimates have been determined across the whole of the northern hemisphere polar ionosphere. The data cover the interval from 2000 to 2005 inclusive.
