Temperature corrections in the Priestley–Taylor equation of evaporation
The Priestley–Taylor equation (PTE) is frequently applied in actual areal evapotranspiration (ET) estimation methods for obtaining the maximum daily rate of evaporation with data from sub-humid conditions. Since PTE was parameterized under humid conditions, a temperature correction is necessary to avoid overestimation of the maximum rate of ET. Wet-environment surface temperature (Tws), a proxy...
متن کاملestimate of unsteady evaporation from bare soils by zero flux plane (zfp) method and comparison with water balance model
evaporation from the soil surface has an important role in the water balance model in nature, so that the major part of rain fall and irrigation water in arid and semi-arid regions is lost via evaporation from the soil surface. in such areas, there are some regions with high water table and because of evaporation from the soil surface, salts accumulation also occur in the soil surface. so evapo...
متن کاملOn Uncertainties of the Priestley-Taylor/LST-Fc Feature Space Method to Estimate Evapotranspiration: Case Study in an Arid/Semiarid Region in Northwest China
Accurate evapotranspiration (ET) estimation is very crucial for water resource management, particularly for the arid and semi-arid region. The remote sensing-based Priestley-Taylor method (RS-PT method) can estimate ET at regional scale, using the feature space of remotely sensed land surface temperature (LST) and vegetation index (VI). This study evaluates the RS-PT feature space method over a...
متن کاملEvaluation of Eight Evaporation Estimation Methods in a Semi-arid Region (Dez reservoir, Iran)
Establishing satisfactory estimation methods of lake evaporation has been crucial vital for research and management of water resources and ecosystems. Determining the accurate method to estimate evaporation from reservoirs in the investigation and management of water resources is very important. Hence, in this study eight empirical methods such as; Makkink, DeBruin-Kejiman, Penman, Priestley-Ta...
