Evaluation of METRIC model for mapping the energy balance components and actual evapotranspiration of a super-intensive drip-irrigated olive orchard

  • Abstract:

    A field experiment was carried out to evaluate the METRIC (Mapping EvapoTranspiration at high Resolution Internalized with Calibration) model for mapping net radiation (Rn), soil heat flux (G), sensible heat flux (H), latent heat flux (LE), actual evapotranspiration (ETa) and crop coefficient (Kc) of a superintensive drip-irrigated olive (Olea europeae L. cv Arbequina) orchard located in Pencahue Valley, Region del Maule, Chile (35 23' LS; 71 44' LW; 96 m above sea level). The study was conducted in an experimental plot of 21.1 hectares using 9 satellite images (Landsat 7 ETM+) acquired on clear sky days during 2011/2012 and 2012/2013 growing seasons. Specific functions to estimate Gi, leaf area index (LAI) and aerodynamic roughness length for momentum transfer (Zom) for olive orchards were incorporated in the standard METRIC model. The performance of the METRIC model was evaluated at the time of satellite overpasses using measurements of LE and H obtained from an eddy correlation system. Performance of the METRIC model was quite good and indicates that Landsat thermal satellite technology is capable of being employed operationally to estimate and manage water consumption of intensive olive production in water-scarce areas of Chile and elsewhere
