Water Resources Management, 2011
The study at first recalls the concept of "potential evapotranspiration" (PET), originally considered equal to the evaporation climatic demand; then, it reminds the steps of its progressive evolution toward the concept of "reference crop evapotranspiration" (ET0) determined on irrigated grass. A physical analysis conducted on the evaporation process is

Journal of Irrigation and Drainage Engineering, 2008
In Nebraska, historically, there have been differences among the water regulatory agencies in terms of the methods used to compute reference evapotranspiration ( ETref ) to determine actual crop water requirements and hydrologic balances of watersheds.

Ability of stochastic modelling to forecast crop reference evapotranspiration*
Irrigation and Drainage, 2021AbstractThe main objective of this study is to evaluate the ability to forecast seasonal and non‐seasonal monthly reference plant water consumption (ET0) with the Box–Jenkins approach (autoregressive integrated moving average), the abbreviation of which is ARIMA (indicated as SARIMA for seasonal series).

EFFECT OF PAN DIAMETER ON EVAPORATION AND REFERENCE CROP EVAPOTRANSPIRATION
Transactions of the ASAE, 2004The effect of pan size on evaporation rates, pan coefficient, and reference crop evapotranspiration is not clearly understood. Evaporation rates (mm/day) were therefore measured using the standard class A pan, a half-standard pan (half the diameter of the class A pan), and quarter-standard pan between February 1 and April 30, 2000, at St.

Study of reference crop evapotranspiration in I.R. of Iran
Agricultural Water Management, 2006Accurate estimation of regional evapotranspiration (ET) is essential for many agricultural water related studies. The data from 81 weather stations, with at least 30 years of data during the period of 1956 2000, were used for estimation of reference crop ET (ET0) in Iran.

Wavelet network model for reference crop evapotranspiration forecasting
2007 International Conference on Wavelet Analysis and Pattern Recognition, 2007Reference Crop Evapotranspiration(RCE) plays an important role in the agricultural production management. RCE characterized by its nonlinearity and multi-time scale feature, may vary with the change of time under the influence of stochastic variation of meteorological factors such as temperature, sunlight, wind speed and so on.

Agricultural Water Management, 2016
Abstract Despite of the great advancement of technologies for water supply, irrigation management remains inadequate in most areas. The lack of basic information on crop water needs is one of the causes for inadequate water use and irrigation management.

Transactions of the ASABE, 2012
Precipitation and reference evapotranspiration are two important variables in hydrologic analyses, agricultural crop production, determining actual crop evapotranspiration and irrigation water requirements, and irrigation management. Both variables vary in space and time, and the weather networks that measure or quantify and report both variables are ...

Evaluation of Reference Crop Evapotranspiration Equations in Various Climates
Water Resources Management, 2009Evapotranspiration is one of the most important elements for quantifying available water since it generally constitutes the largest component of the terrestrial water cycle. This study evaluated four models (Makkink, Turc, Priestley–Taylor and Hargreaves) commonly used to estimate monthly reference crop evapotranspiration (ETo) values.
