Estimation of evapotranspiration plays an important role in understanding the water cycle on the earth, especially the water budget in agricultural ecosystems. The parameterization approach of the Penman-Monteith-Katerji-Perrier (PM-KP) model, accounting for the influence of meteorological variables and aerodynamic resistance on surface resistance, was proposed in the literature, but it has not...

Abstract This study aimed to accurately estimate daily wheat evapotranspiration using two remote sensing algorithms, Surface Energy Balance System (SEBS) and Algorithm for Land (SEBAL), in central Khuzestan province during 2019–2020. The results of algorithms were compared with lysimeter (as a direct method), FAO-Penman–Monteith (FAO-PM), temperature-based methods (Hargreaves-Samani Blaney-Crid...

Today, accurate irrigation approaches are of great importance due to climate change and a decrease in water resources. FAO methodology based on reference evapotranspiration (ET0) crop coefficients (Kc) commonly used worldwide determine requirements (ETc). Kc values different plants for areas can be taken from FAO-56 FAO-24. However, must determined or calibrated every relevant region because th...

A evapotranspiração de referência (ETo) é importante para a agricultura irrigada e sua relação com o Kc da cultura determina Evapotranspiração (ETc). Organização das Nações Unidas Alimentação Agricultura (FAO) determinou como padrão método Penman Monteith estimativa ETo, porém existem diferentes fórmulas empíricas tal aplicação, sendo assim presente trabalho tem objetivo avaliar referencia por ...

Evapotranspiration is an important parameter to know in the management of agricultural water resources. There are several methods for estimating evapotranspiration (ETo). The FAO Penman-Monteith method considered universal standard ETo, however, climate data needed calculate ETo not always available, so it necessary evaluate performance using equations as a comparison evapotranspiration. This s...

The need for accurate estimates of reference crop evapotranspiration (ETo) is important in irrigation planning and design, scheduling, reservoir management among other applications. ETo can be accurately determined using the internationally accepted FAO Penman–Monteith (FAO-56 PM) equation. However, this requires numerous observed data, including solar radiation, air temperature, relative humid...
