Estimation of Crop Evapotranspiration by Means of the Penman-Monteith Equation [PDF]

open access: yes, 1991
This study evaluated the potential of using simple, semi-empirical resistance models for the direct estimation of crop evapotranspiration as an alternative to the traditional approach involving a reference equation and a crop coefficient. It consisted of three major parts. The first part originally aimed at the development of simple expressions for the

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 ...

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

Estimation methods of reference evapotranspiration (ETo) for Uberlândia -MG [PDF]

open access: yesEngenharia Agrícola, 2015
One approach to verify the adequacy of estimation methods of reference evapotranspiration is the comparison with the Penman-Monteith method, recommended by the United Nations of Food and Agriculture Organization - FAO, as the standard method for ...
