Comparison of methods for estimating reference evapotranspiration (ETo) for Rahuri region
Journal of Agrometeorology, 2015 Penman Monteith (FAO56-PMM), Modified Penman FAO-24 (MPM), Hargreaves-Samani (HSM), FAO-24 Pan Evaporation (FPEM), Blaney-Criddle (BCM) and FAO Radiation (FRM) methods were used for estimation of ETo for Rahuri region.

Irrigation and Drainage, EarlyView.ABSTRACT Climate change is making water availability more uncertain, with growing consequences for the productivity and long‐term sustainability of tropical and subtropical fruit orchards. Mangifera indica L. and Persea americana Mill. both require large amounts of water to sustain growth and productivity.

Comparison of the reference crop evapotranspiration estimated by the Penman-Monteith and Penman methods in Tarim River Basin [PDF]
, 2005 Based on the daily meteorological data in Aksu water balance experimental station in Tarim River Basin from 1989 to 1996, the reference evapotranspirations (ET0) calculated by the Penman-Monteith and Penman methods were compared.

Penman-Monteith与Penman修正式计算塔里木盆地参考作物潜在腾发量比较 [PDF]
, 2005 利用1989～1996年阿克苏水平衡试验站的气象资料,对Penman-Monteith公式和Penman修正式计算的参考作物潜在腾发量进行了比较。Penman修正式计算的参考作物潜在腾发量年值略大于Penman-Monteith公式计算的年值,绝对偏差为42～128mm,相对偏差为3.3～9.8%,且年际间变化不大。各月的参考作物潜在腾发量变化较大,绝对偏差可正可负,1、2、12月小于0,3～10月大于0,相对误差1、12月较大,2、11月较小,其它月份变化不大 ...

Irrigation and Drainage, EarlyView.ABSTRACT Accurate estimation of reference evapotranspiration (ET0) and crop coefficients (Kc) is critical for irrigation planning, particularly in data‐limited regions where agriculture dominates freshwater consumption. Although machine learning (ML) methods have been widely applied to ET0 and Kc estimation, most studies address these parameters ...

Irrigation and Drainage, EarlyView.ABSTRACT Long‐term economic analyses of variable rate irrigation (VRI) strategies were performed compared with uniform irrigation management (UIM) in a reference production field using the AquaCrop model. Five strategies to trigger irrigation were as follows: (Field Capacity‐VRI, Driest Soil Trigger‐VRI, Water Mining‐VRI, Conventional Uniform ...

Practical and Theoretical Benefits of an Alternative to the Penman‐Monteith Evapotranspiration Equation [PDF]
Water Resources Research, 2020 AbstractThe Penman‐Monteith equation is used widely to estimate evapotranspiration (E) and to understand its governing physics. I present an alternative to the Penman‐Monteith equation that has both practical and theoretical advantages, at no appreciable cost.
