Wind Data & Reports


AWS Truepower’s data and maps are derived from simulations of historical atmospheric conditions performed by a numerical weather prediction (NWP) model. Most of these products are available through the Windnavigator platform. The model output is further downscaled with a microscale model accounting for local terrain and surface influences, and adjusted using available high-quality wind measurements. Our approach has been thoroughly validated and uncertainty statistics are available.
