We examine the existing measurements of global solar radiation and sunshine duration for Italy, and evaluate the errors made in estimating global solar radiation from sunshine hours measurements. We find that the Ångstrom–Black linear relation in the form F/Fext = 0.23 + 0.37n/N can be used to predict global solar radiation over all of Italy with a relative error of ∼10%; whereas, if the average value of F/Fext for all stations is used as a simple predictor, the relative error turns out to be ∼15%.
