Global Wind Atlas 2.0 launched

Tuesday 05 Dec 17
The World Bank has just launched a new global wind atlas that considers the impacts of high-resolution climatology and topography on the wind resource by employing meso- and microscale modelling. The WAsP models were selected as the microscale modelling system used for mapping the worlds wind resources in detail.

The Global Wind Atlas (GWA 2.0) provides new global data sets of wind resource data, accounting for high-resolution climatology and topography and using a unified and documented methodology. The main difference compared to GWA 1.0 is that the wind-climatological inputs to the microscale modelling now comes from 9-km mesoscale modelling of the entire globe done by Vortex SL.

GWA 2.0 was specifically designed for wind power planning and modelling on national, regional and global scales. It can be used to identify potential high-wind areas for wind power generation virtually anywhere in the world, and perform preliminary calculations. However, the atlas cannot be used for accurate prediction of specific wind turbines and wind farms; though it may provide valuable information for e.g. project preparation and design of measurement campaigns.

The new tool facilitates online queries and provides freely downloadable datasets based on the latest input data and modeling methodologies. Users can additionally download high-resolution maps showing global, regional, and country wind resource potential in the Downloads section. Information on the datasets and methodology used to create the Global Wind Atlas can be found in the Methodology and Datasets sections of the GWA web site.
