Abstract

This study aimed to generate accurate evapotranspiration (ETA) data for the Mountain Aquifer region using the SEBAL model in Google Earth Engine (GEE) with a resolution of 30 m. The analysis provided valuable insights into evapotranspiration's spatial and temporal dynamics and its relationship with land use characteristics. Significant spatial and temporal variations in ETa were observed, ranging up to 2400 mm/year with an average of 600-800 mm/year. The generated data is then compared to the results obtained utilizing FAO's WaPOR product for the ETA calculation. Comparisons with previous studies highlighted the variability of ETa values due to different methodologies and spatial resolutions. The ETa values obtained in this study aligned with the average range reported by earlier research. However, discrepancies were observed with the FAO's WaPOR product, primarily due to methodological limitations and variations in parameter values across land use types.
