Improvement of Makkink model for reference evapotranspiration estimation using temperature data in Northwest China

Reference evapotranspiration (ET0) is an important parameter for climatological and hydrological studies, as well as for agricultural water resources management. In this study, 7 temperature-based solar radiation models were adopted to improve the Makkink model for ET0 estimation in Northwest China. The temperature-based models only require air temperature as input data, which can be easily monitored in most areas around the world. The...
