Wind atlas

A wind atlas contains data on the wind speed and wind direction in a region. These data include maps, but also time series or frequency distributions. A climatological wind atlas covers hourly averages at a standard height (10 meter) over even longer periods (30 years). But depending on the application there are variations in averaging time, height and period.

A wind atlas is employed when pre-selecting wind farm sites. The required data include 10-minute averaged wind at heights between 30 and 100 meter over a 10 to 20-year period.

At least one wind atlas covers the globe, and other wind atlases cover the EU12 countries and the European offshore regions. Wind atlases have also been compiled for many countries or regions.
