A wind rose diagram provides a graphical representation of how wind speed and direction are distributed at a site. Data are plotted on a polar coordinate system, with spokes emanating from the center. Each spoke represents a specific wind direction and the length of the spoke represents the wind speed. The color bands within a spoke show the distribution of wind ranges.

You must first register for a free account on the website. Data can then be downloaded either through the "Data Selector" menu option or the "gear" icon at the upper right of each graph. The data selector provides access to all the sites and parameters within the entire data set. Downloading data through the "gear" icon only provides access to the data currently displayed.
