A Comparative Study of Potential Evapotranspiration Estimation by Eight Methods with FAO Penman–Monteith Method in Southwestern China
Potential evapotranspiration (PET) is crucial for water resources assessment. In this regard, the FAO (Food and Agriculture Organization)–Penman–Monteith method (PM) is commonly recognized as a standard method for PET estimation. However, due to requirement of detailed meteorological data, the application of PM is often constrained in many regions. Under such circumstances, an alternative metho...
متن کاملestimation evapotranspiration by penman monteith method and its water require in isfahan province
water productivity increase is one of the water management solutions in agriculture and increasing its efficiency. the accurate determination of plants water requirement and the accurate value estimate of evapotranspiration is essential for improving water productivity in irrigation network that it can help to improve water management in agriculture. in this research such climatic elements as t...
متن کاملtemperature- and radiation based methods against the standard fao penman- monteith for estimating the reference evapotranspiration (et0) in gorgan
the fao penman - monteith (f-p-m) method is now broadly accepted as the standard for estimating the reference evapotranspiration (et0). the method is also now used for evaluating the temperature-based [blaney-criddle (b-c) and hargreaves-samani (h-s)] and radiation-based [jensen-haise (j-h) and turc (tc)] methods. the objective was to compare the et0 estimated by the b-c, h-s, j-h, tc methods w...
متن کاملEstimating Daily Global Evapotranspiration Using Penman-Monteith Equation and Remotely Sensed Land Surface Temperature
Daily evapotranspiration (ET) is modeled globally for the period 2000–2013 based on the Penman–Monteith equation with radiation and vapor pressures derived using remotely sensed Land Surface Temperature (LST) from the MODerate resolution Imaging Spectroradiometer (MODIS) on the Aqua and Terra satellites. The ET for a given land area is based on four surface conditions: wet/dry and vegetated/non...
متن کاملارزیابی مدل MSM جهت پیش‌بینی تبخیر- تعرق ذرت دانه‌ای و مقایسه نتایج آن با مقادیر حاصله از روش‌های پیشنهادی فائو 56
Optimal crop water requirement is needed for precise irrigation scheduling. Prediction of crop water requirements is a basic factor to achieve this goal. In this study, maize potential evapotranspiration (ETp) was prediced by maize simulation model (MSM). Then, it was evaluated and validated using experimental field data obtained in Agricultural Research Station of Shiraz University (Bajghah, F...
