英文摘要	The evapotranspiration-based scheduling method is the most common method for irrigation programming in agriculture. There is no doubt that the estimation of the reference evapotranspiration (ETo) is a key factor in irrigated agriculture. However, the high cost and maintenance of agrometeorological stations and high number of sensors required to estimate it make it non-plausible, especially in rural areas. For this reason, the estimation of ETo using air temperature, in places where wind speed, solar radiation and air humidity data are not readily available, is particularly attractive. A daily data record of 49 stations distributed over Duero basin (Spain), for the period 20002018, was used for estimation of ETo based on seven models against Penman-Monteith (PM) FAO 56 (FAO - Food and Agricultural Organization of the United Nations) from a temporal (annual or seasonal) and spatial perspective. Two Hargreaves-Samani (HS) models, with and without calibration, and five Penman-Monteith temperature (PMT) models were used in this study. The results show that the models' performance changes considerably, depending on whether the scale is annual or seasonal. The performance of the seven models was acceptable from an annual perspective (R-2 > 0.91, NSE > 0.88, MAE < 0.52 and RMSE < 0.69 mm d(-1); NSE - Nash-Sutcliffe model efficiency; MAE - mean absolute error; RMSE - root-mean-square error). For winter, no model showed good performance. In the rest of the seasons, the models with the best performance were the following three models: PMTCHU (Penman-Monteith temperature with calibration of Hargreaves empirical coefficient - k(RS), average monthly value of wind speed, and average monthly value of maximum and minimum relative humidity), HSC (Hargreaves-Samani with calibration of k(RS)) and PMTCHU (Penman-Monteith temperature without calibration of k(RS), average monthly value of wind speed and average monthly value of maximum and minimum relative humidity). The HSc model presents a calibration of the Hargreaves empirical coefficient (k(RS)). In the PMTCUH model, k(RS) was calibrated and average monthly values were used for wind speed and maximum and minimum relative humidity. Finally, the PMTCUH model is like the PMTCUH model except that k(RS) was not calibrated. These results are very useful for adopting appropriate measures for efficient water management, especially in the intensive agriculture in semi-arid zones, under the limitation of agrometeorological data.
