Wind Roses at 30m
Frequency distribution of wind by sector
Latitude = 47.218, longitude = -66.468

Warning: The first column of the wind rose files shows the wind direction computed in degrees starting from the east then rotating counterclockwise --> 0 degree = east, 90 degrees = north.

Note: the maximum scale of the wind roses is of 0.3 in most cases, to allow a better visual comparison between the roses. However, when a value over 0.3 is found in a data file, the maximum scale is modified to reflect these higher values. Then a warning appears above the wind rose.
