Abstract: Evapotranspiration (ET) plays a critical role in watershed hydrology, influencing runoff and sediment yield. The accuracy of ET data is critical for reliable simulations in hydrological models such as the Annualized Agricultural Non-Point Source (AnnAGNPS) model. This study examines the Pelahatchie Bay watershed, covering an area of 248.83 km² in Rankin County, Mississippi, and compares two ET data sources: the satellite-derived Terra MODIS product and the NOAH Land Surface Model from the North American Land Data Assimilation System (NLDAS-2). Additionally, AnnAGNPS’s internal ET estimation, based on the Penman-Monteith equation, is evaluated for comparison.
