Anticoincidence (left) and Null-anticoincidence (right) of wind power density, at 50 m.

Units indicate the number of grid points in a ∼1000×1000 km box surrounding the gridpoint in question which are anticoincident to the central gridpoint, which is when the hourly time series of WPD is greater than 200 W m-2 at one of the two points, but not both, for 50% of the total length of the time series.
