    • Data quality for the Global Renewable Energy Atlas – Solar and Wind (Concept paper)

      The Global Atlas for Renewable Energy provides access to a vast range of solar and wind resource maps created using different methodologies, with different spatial coverage and resolutions. Several datasets may overlap a single territory, and users can choose among several data sources. Yet this very versatility can pose a dilemma for the end-user over the main strengths and weaknesses of the available datasets, and which data is the most suitable to use.
