The Global Wind Atlas version 3.1 includes several new features and improvements. All visual layers on the Global Wind Atlas have become user-scaleable and the new bathymetry layer makes it possible to quickly assess the water depth for offshore wind turbines and wind farms.

Today, DTU Wind Energy has released the Global Wind Atlas (GWA) version 3.1. This new version of the free and web-based application represents a significant upgrade. As such, the GWA continues to help policymakers, planners and investors identify global, national, regional and local high-wind areas for wind power generation. DTU would like to acknowledge the funding provided by ESMAP, as well as advice and review provided by staff and consultants from the World Bank

In GWA 3.1, DTU Wind Energy and Nazka Mapps introduce an important improvement, which facilitates that all visual layers on the GWA have become user-scaleable. So now, the users are able to choose between different color scales and set minimum and maximum values for each map. 

GWA users who are interested in offshore wind resources will appreciate the new “bathymetry” layer, which includes negative elevation for seabed bathymetry, drawing on data provided by the General Bathymetric Chart of the Oceans (GEBCO). This makes it possible to quickly assess the water depth for offshore wind turbines and wind farms. 

In the “countries and regions” section, a link has been included to the results of the World Bank Group’s analysis of offshore wind technical potential for emerging markets around the world. These maps show the estimated technical potential for fixed and floating offshore wind in in terms of installed power capacity, within 200 kilometers of the shoreline. 

Engineers and researchers will appreciate that orography, Weibull-A and Weibull-k layers have been added to the existing GIS download feature by country.

Ooooh this looks like a fun toy to play with! Such a simple way to poke around and see why some areas are far ahead with wind, and why my home in Florida will likely never be a wind hub (good thing we have the solar resources to fall back on!)
