Comparison of two methods to derive time series of actual evapotranspiration using eddy covariance measurements in the southeastern Australia

A dynamic surface conductance to predict crop water use from partial to full canopy cover

“…The good data-model agreement between measurements and predictions of ET confirmed the strengths of the P-M equation as a model framework and the robustness of the dynamic G s model. The slight differences between predictions and measurements are well within the errors of measured ET, which were consistent with previous studies (Katerji and Rana, 2006;Liu et al, 2012). In this study, the accurate prediction of ET might be mainly attributed to most of the variations of ET driven by available energy obtained (Ding et al, 2013;Kool et al, 2014).…”

Comparative analysis of reference evapotranspiration equations modelling by extreme learning machine

“…Reference evapotranspiration (ET 0 ), introduced by the United Nations Food and Agriculture Organization (FAO) as a methodology for computing crop evapotranspiration (Doorenbos and Pruitt, 1977), can be measured using lysimeter, eddy covariance systems, bowen ratio-energy balance, scintillometer (Benli et al, 2006;Miranda et al, 2006;Williams and Ayars, 2005;Liu et al, 2013Liu et al, , 2012Savage, 2009;Savage et al, 2009) or calculated using equations based on temperature, radiation or pan evapouration or combination-type equations. ET 0 is needed for the management of water resources, irrigation scheduling and agricultural production.…”

Modeling crop water use in an irrigated maize cropland using a biophysical process-based model

“…Crop water use or evapotranspiration (ET) is the largest term in the cropland water balance after precipitation and irrigation (Leuning et al, 2008;Liu et al, 2012) because more than 90% of water used in agriculture is lost by soil evaporation and crop transpiration, referring as to ET (Rana and Katerji, 2000). Thus, accurate determination of crop ET is required to better understand terrestrial hydrological cycles and improve our ability to use limited water resources efficiently (Ding et al, 2013a;Zhang et al, 2011a).…”

“…In practice, daily ET is very important to develop precision irrigation scheduling and improve water use efficiency (Allen et al, 1998;Ding et al, 2013b;Liu et al, 2012). The improved ACASA can also well simulated E s before and after irrigation and precipitation events, indicating that the approach of ground resistance for evaporation adopted in the improved ACASA was appropriate.…”
