Uncertainty in estimating reference evapotranspiration using remotely sensed and forecasted weather data under the climatic conditions of Southern Spain

In this study, a detailed spatial analysis of the reference evapotranspiration ( ET o ) estimates provided by the MAK ‐Adv approach and the well‐known Penman‐Monteith equation ( PM‐FAO56 ) has been carried out. MAK ‐Adv approach considers a regionally calibrated Makkink equation based on a combination of remotely sensed solar radiation, R s , provided by the Land Surface Analysis Satellite Applications Facility ( LSA SAF ), and numerical weather...
