| Abstract: |
| By using the calculation results of Penman-Monteith FAO 56 as standard values, four models including Makkink model, Turc model, Priestley-Taylor model and Hargreaves model, which were commonly used to estimate daily reference crop evapotranspiration values, were evaluated to determine the suitable model for estimating ET0 with few data requirements and high accuracy for north Tarim Basin. The results showed that Turc model was the best model in estimating ET0, followed by Makkink model and Priestley-Taylor model, but Hargreaves model turned out to be the most imprecise model in the study area. |
