Canopy resistance is a key parameter in the Penman?Monteith (P?M) equation for calculating evapotranspiration (ET). In this study, we compared a machine learning algorithm?support vector machine (SVM) and an analytical solution (Todorovic, 1999) for esti...

Most of the current parameterization schemes for the Penman?Monteith?Leuning evapotranspiration (ET) model (PML) consider meteorological and energy factors and land use types, but the analysis of the effect of soil moisture (SM) changes on ET processes l...

The FAO 56 Penman?Monteith equation (PM) is considered the most accurate method for estimating reference evapotranspiration (ETo). However, PM requires a large amount of data that is not always available. Thus, the objective of this study is to improve t...
