Optimal Calibration of Evaporation Models against Penman–Monteith Equation [PDF]
Water (Switzerland), 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
Eng, 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

Leaf-scale experiments reveal an important omission in the Penman–Monteith equation [PDF]
Hydrology and Earth System Sciences, 2016 Abstract. The Penman–Monteith (PM) equation is commonly considered the most advanced physically based approach to computing transpiration rates from plants considering stomatal conductance and atmospheric drivers. It has been widely evaluated at the canopy scale, where aerodynamic and canopy resistance to water vapour are difficult to estimate directly,
