The Food and Agricultural Organization of the United Nations (FAO) Penman–Monteith (PM) method is widely regarded as most effective reference evapotranspiration (ETo) estimator; however, it requires a wide range data that may be scarce in some rural regions. When feasible relative humidity, solar radiation wind speed are unavailable, temperature-based useful to estimate ETo provide suitable sup...

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 not always available. Thus, objective this study to improve Hargreaves–Samani (HS) estimates in Peruvian Altiplano (PA) by calibrating radiation coefficient KRS. results show modified HS (HSM) ETo at validation after ...

Estimation of evapotranspiration (ET) for alpine meadow areas in the Tibetan Plateau (TP) is essential for water resource management. However, observation data has been limited due to the extreme climates and complex terrain of this region. To address these issues, four representative methods, Penman-Monteith (PM), Priestley-Taylor (PT), Hargreaves-Samani (HS), and Mahringer (MG) methods, were ...

an accurate determination of evapotranspiration is required for many studies that involve estimation of the water balance. one methodology is the use of lysimeters. considering the semiarid climate of kerman province, in southeastern parts of iran, the only operating electronic weighing lysimeter in the country was used for calculating daily eto from april 2004 to march 2005 in three different ...

Estimating daily evapotranspiration is challenging when ground observation data are not available or scarce. Remote sensing can be used to estimate the meteorological data necessary for calculating reference evapotranspiration ETo. Here, we assessed the accuracy of daily ETo estimates derived from remote sensing (ETo-RS) compared with those derived from four ground-based stations (ETo-G) in Kur...

The proposed method for calculation of potential evapotranspiration is Penman-Monteith FAO method, but there are other methods that require less meteorological data but estimates close to the FAO Penman-Monteith method in different climatic conditions.  Performance evaluation of these methods on the same basis is prerequisite for selecting an alternative approach in accordance with available da...

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 ...
