Here are fields of wind velocity, vorticity, and divergence for the period 16:25-16:32 UTC calculated from cross-correlations of VIL backscatter data. These fields were then added to a map of the Lake Michigan shoreline at Sheboygan. The VIL was located at the origin (Upper left-hand corner) of the axes.
