evaluation and calibration of reference evapotranspiration models according to calculating periods for a cold semi-arid climate
in agricultural practices, reference evapotranspiration (et0) parameters need to be specified for crop water requirement determination. although, the crop water requirement is not an easy task. numerous mathematical models and experimental methods have been developed for this purpose in the entire world. on the other hand, ten-daily and monthly average meteorological data are used in many of ir...
متن کاملAssessing Experimental and Intelligent Models in Estimating Reference Evapotranspiration
Introduction: As the most important element in the hydrologic cycle which depends on climate variables such as near-ground wind speed, air temperature, solar radiation, and relative humidity, reference evapotranspiration (ET0) is normally computed through a variety of methods, each of which requires different and in some cases extensive data that are unavailable in many circumstances, especial...

متن کاملEvaluation of evapotranspiration methods for model validation in a semi-arid watershed in northern China
This study evaluates the performance of four evapotranspiration methods (Priestley-Taylor, Penman-Monteith, Hargreaves and Makkink) of differing complexity in a semiarid environment in north China. The results are compared to observed water vapour fluxes derived from eddy flux measurements. The analysis became necessary after discharge simulations using an automatically calibrated version of th...
متن کاملEstimating Daily Reference Evapotranspiration in a Semi-Arid Region Using Remote Sensing Data
Estimating daily evapotranspiration is challenging when ground observation data are not available or scarce. Remote sensing can be used to estimate the meteorological data necessary for calculating reference evapotranspiration ETo. Here, we assessed the accuracy of daily ETo estimates derived from remote sensing (ETo-RS) compared with those derived from four ground-based stations (ETo-G) in Kur...
