The aimis to explore the effectiveness of a range of variables for modelling horizontal ultraviolet irradiancethrough a comparison of supervised artificial neural network (ANN) and regression model results.A preliminary feature selection process using the Pearson correlation coefficient was sufficient todetermine the variables for use in the models. The following variables and their influence on horizontal ultraviolet irradiance were analyzed: horizontal global irradiance (IGH), clearness index (kt),solar altitude angle (α), horizontal beam irradiance (IBH), diffuse fraction (D), temperature (T), skyclearness (ε), cloud cover (Cc), horizontal diffuse irradiance (IDH), and sky brightness (∆). The ANNmodels yielded results of greater accuracy than the regression models.
