Reference evapotranspiration (ET o ) assessment at regional scale is a challenge to agricultural and hydrological research requiring the characterization of vast areas to obtain accurate meteorological variables. To account for this, a new approach considering a modified version of the Makkink equation and based on a combination of remotely sensed solar radiation (R s ) considering the MSG satellite, and numerical weather forecast of near surface air temperature (T 2m ), was developed. The new approach is referred as Makkink-Advection equation (MAK-Adv).
