Estimating 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...
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 Methods For Estimating Daily Reference Crop Evapotranspiration At A Site In The Humid Southeast United States
Estimated daily reference crop evapotranspiration (ETo) is normally used to determine the water requirement of crops using the crop factor method. Many ETo estimation methods have been developed for different types of climatic data, and the accuracy of these methods varies with climatic conditions. In this study, pair−wise comparisons were made between daily ETo estimated from eight different E...
متن کاملevaluation of pan coefficients from ann, anfis, and empirical methods, for estimation of daily reference evapotranspiration
introduction: evaporation and evapotranspiration are two major components of hydrological cycle which are very important for agricultural studies as well as water resources management. so far, various methods have been addressed for the estimation of daily reference crop evapotranspiration (et0). among them, fao penman-montieth 56 (pmf-56) (allen et al., 1998) is widely used as a standard metho...
متن کاملUsing remotely sensed solar radiation data for reference 1 evapotranspiration estimation at a daily time step
16 Solar radiation is an important climatic variable for assessing reference evapotranspiration 17 (E0), but it is seldom available in weather station records. Meteosat satellite images processed 18 with the Heliosat-2 method provide the HelioClim-1 database, which displays spatialized 19 solar radiation data at a daily time step for Europe and Africa. The aim of the present work 20 was to inve...
