Estimation of daily tomato evapotranspiration using the Penman-Monteith

open access: yesInternational Journal of Agriculture and Natural Resources, 2000
The study was carried out to evaluate daily evapotranspiration, using the Penman-Monteith equation, with variable canopy resistance, over a tomato crop, at the Panguilemo Experimental Station located 11 km north of Talca (35°23’13” LS and 71°40’42” LW at 110 m.a.s.1.).

Nonlinearities of Penman and Penman-Monteith Equations across Multiple Timescales

open access: yes, 2023
The nonlinear Penman and Penman-Monteith equations, widely used for estimating surface evapotranspiration at regional and global scales, were derived from turbulent transport of heat fluxes and thus apply to subhourly scale. However, these equations have been directly applied with hydrometeorological variables averaged at longer time intervals, leading

The sensitivity of the PDSI to the Thornthwaite and Penman-Monteith parameterizations for potential evapotranspiration [PDF]

open access: yesJournal of Geophysical Research, 2011
[1] Potential evapotranspiration (PET) is one of the inputs to the Palmer Drought Severity Index (PDSI). A common approach to calculating PDSI is to use the Thornthwaite method for estimating PET because of its readily available input data: monthly mean temperatures.

Optimal Calibration of Evaporation Models against Penman–Monteith Equation [PDF]

open access: yesWater, 2021
We present an approach for the calibration of simplified evaporation model parameters based on the optimization of parameters against the most complex model for evaporation estimation, i.e., the Penman–Monteith equation. This model computes the evaporation from several input quantities, such as air temperature, wind speed, heat storage, net radiation ...

THE AMOUNT OF WATER SHOULD BE APPLIED FOR FABA BEAN CROP UNDER DRIP AND DEFICIT IRRIGATION. [PDF]

open access: yesJournal of Soil Sciences and Agricultural Engineering, 2014
A field experiment was carried out during the two successive growing seasons of faba bean 2011/ 2012 and 2012/ 2013. The aim of this investigation was to find out the impact of water deficit based on differentreference evapotranspiration( ETₒ) methods ...

Assessment of Artificial Neural Network through Drought Indices

open access: yesEng, 2022
Prediction of potential evapotranspiration (PET) using an artificial neural network (ANN) with a different network architecture is not uncommon. Most researchers select the optimal network using statistical indicators. However, there is still a gap to be
