Forecasting of reference crop evapotranspiration
Agricultural Water Management, 1993Abstract The first step in the determination of irrigation water requirements for use in project planning, design, and operation commonly involves the prediction of the reference crop evapotranspiration. This paper presents a simple mathematical model for forecasting reference crop evapotranspiration at three stations in California that represent ...

Estimating Reference Crop Evapotranspiration with ETgages
Journal of Irrigation and Drainage Engineering, 2009Three years of daily reference evapotranspiration measured by atmometers ( ETg ) were compared to the values computed from the ASCE standardized Penman–Monteith equation ( ETr ) using co-located me...

Reference and Crop Evapotranspiration
2012Advancements have been made in estimating potential and reference evapotranspiration. Actual crop evapotranspiration estimation still is a challenge due to limited availability of local crop coefficients and large-scale variation in field conditions.

Estimating reference crop evapotranspiration using HGA-LSSVM
2010 Sixth International Conference on Natural Computation, 2010Reference crop evapotranspiration (ETo) is the basis for estimating crop evapotranspiration and for computing crop irrigation requirements. In recent years, Least squares support vector machines (LSSVM) have been applied to forecasting in many areas of engineering. In this paper, a novel hyper-parameter selection for LSSVM regression is presented based
