Hello community, for my master-thesis among other things I plan to work with the Solar radiation tool (10.3). In the paper "A comparative analysis of DEM-based models to estimate the solar radiation in mountainous terrain - Ruiz-Arias et al (2009)" I saw that there is maybe a not satisfying accuracy of the tool. Solar irradiance was underestimated, especially on days with a low clearness-index. Did anybody make experiences in this regard? Or was the tool revised since than maybe? Thank you in advance for your help. Andreas Rechenmacher
