A method of calibration and variance analysis with respect to the Penman-Monteith equation for the Turc, Hargreaves and Abtew potential evapotranspiration models
Introduction: The full ASCE/FAO-56 Penman-Monteith evapotranspiration (PM-ET) equation and crop coefficients are often employed for irrigation scheduling of open-field crops. To obtain PM-ET derived water-use figures requires access to full weather station datasets, which includes radiation, air temperature, wind-speed, and relative humidity measurements. Over the years there have been many ...

Analysis of potential evapotranspiration using 11 modified temperature–based models
The evapotranspiration was estimated using 11 temperature–based models and was compared with the FAO Penman–Monteith model. The results showed that the modified Hargreaves–Samani models estimate the evapotranspiration better than the other models in the most provinces of Iran. However, the values of R² were less than 0.98 for 15 provinces of Iran. Therefore, the models were calibrated and ...
