*2.3. Image Analysis*

In this study, the METRIC model was used to analyze Landsat satellite imagery, producing ET time-series datasets for the study period. The METRIC model description and required inputs based on Landsat satellite datasets are summarized in the literature [6,41]. Several hourly and daily outputs were obtained at the completion of each image analysis. Four daily outputs were obtained including daily ET (mm day<sup>−</sup>1), evaporation fraction (EF) (unitless), leaf area index (LAI) (m2 m<sup>−</sup>2), and normalized difference vegetation index (NDVI) (unitless). Hashem et al. [41] assessed hourly estimation accuracy for ET (mm hr<sup>−</sup>1), net radiation (Rn) (W m−2), soil heat flux (Go) (W m−2), and surface air temperature (Ts) (◦C). A detailed description of the hourly assessment procedure was summarized [38,41].
