This paper describes a detailed evaluation of the performance and characteristic behaviour of feed-forward artificial neural network (ANN) and M5 model tree for estimating reference evapotranspiration (ET<Subscript>0</Subscript>) at four meteorological sites in an arid climate. The input variables for these models...</subscript>
