Evapotranspiration is one of the hydrological cycle’s most important elements in water management across economic sectors. Critical applications agriculture domain include irrigation practice improvement and efficiency, as well resource preservation. The main objective this research to forecast reference evapotranspiration using vector autoregression (VAR) model investigate meteorological varia...

Abstract. Reference crop evapotranspiration (ETo) is calculated using a standard formula with temperature, vapor pressure, solar radiation, and wind speed as input variables. ETo forecasts can be produced when of these variables from numerical weather prediction (NWP) models are available. As raw often subject to systematic errors, statistical calibration needed for improving forecast quality. ...

A simplified equation to estimate spatial reference evapotranspiration (ETo_Ts) from remote sensing-based surface temperature (Ts) and local standard meteorological data is suggested. It is based on a parameterization of the meteorological conditions of the first few meters of the atmosphere through two parameters (a and b) which come from a simpler form of the Penman–Monteith equation:
