| dc.description.abstract | A study was carried out to evaluate the METRIC (Mapping EvapoTranspiration at high Resolution with Internalized Calibration) model to estimate water requirements or actual evapotranspiration (ETa) for a drip-irrigated apple orchard located in the Maule Region, Chile (lat. 35°25'S; long. 71°23'W; 189 m above mean sea level). For estimating ETa using the METRIC model, seven satellite images (Landsat 7 ETM+) acquired during clear sky days were used from the 2012-2013 growing season. The performance of METRIC was evaluated using measurements of ETa from an Eddy Covariance system (EC) at the time of satellite overpass (11:30 h). The statistical analysis indicated that the METRIC model overestimated ETa values by about 7% with a root mean square error (RMSE), mean absolute error (MAE) and index of agreement (d) of 0.42 mm d-1, 0.29 mm d-1 and 0.88, respectively. Main errors of the METRIC model were associated with the selection of the hot pixels which were difficult to obtain for some satellite images. | es_CL |
