Abstract Submission: Evapotranspiration (ETc) from irrigated fields represent the largest and the most uncertain component of hydrological budgets in agroecosystems, including the Eastern Snake Plain Aquifer (ESPA) region. OpenET has filled an important information gap in this respect by delivering spatially continuous ETc estimates from six state of the art remote sensing-based models across Western U.S. Here, we rely on the monthly gridded OpenET ETc product to extract lessons for assessing agricultural water use in the ESPA. We focus on multidimensional aspects of ETc variability stemming from hydroclimatic variation and contrasting crop surfaces as well as uncertainty owing to choice of models, and how these impact our ability to quantify and predict water consumption patterns in the region.
