Sicily monthly high-resolution solar radiation climatologies

We present a methodology developed to estimate solar radiation climatologies starting from a network of global radiation and/or sunshine duration records and a digital elevation model. It allows obtaining high-resolution grids of monthly normal values for direct, diffuse and global radiation on an inclined surface. We discuss the application of the methodology to a data set of 41 Sicilian global radiation records and the resulting 2002-2011 monthly radiation climatologies.
