A Solar Atlas for the Trentino Region in the Alps: Quality Control of Surface Radiation Data

The accurate measurement and assessment of the solar radiation available at the Earth's surface are important for a wide range of energy-related applications. They are particularly challenging in mountainous areas, where orographic effects greatly increase spatial and temporal variability of radiation. In this contribution criteria and outcomes from the quality control of a set of hourly global irradiation observations, collected at the radiometric stations of the Trentino region (Italian Alps) during the years 1987-2012, are presented. The validated dataset will provide the basis for a high-resolution solar atlas of Trentino.
