Seven empirical models and the artificial neural network model (ANN) are applied and validated to estimate the daily and monthly global solar radiation on a horizontal surface in Qena, Upper Egypt. Statistical comparison has been done between all these models. The results demonstrated that ANN model with MBE, RMSE, MPE, R, NSE and t values of -0.0692, 0.5338, 0.2647, 0.9946, 0.9890 and 2.4934 r...

Solar radiation data are an important input for estimating evapotranspiration and modelling crop growth. Direct measurement of solar radiation is now carried out in most European countries, but the network of measuring stations is too sparse for reliable interpolation of measured values. Instead of direct measurements, solar radiation may be estimated from empirical solar radiation models that ...
