Caption

Maps and photos of the study areas, Diamond Valley, Nevada (left), and Harney Basin, Oregon (right). The figure on the far-left shows Diamond Valley evapotranspiration (ET) image data (raster view) from the OpenET ensemble mean for 2022. Irrigated fields are shown in blue. The figure on the top right (field view) shows the ET data from the OpenET ensemble mean (2022) only for irrigated fields in Harney Basin. The researchers rely on satellite remote sensing-derived ET data from OpenET and compare with readings from high-quality magnetic flow meters fitted on the pumps (top center). The pumped groundwater is then applied to the fields using irrigation systems such as the one on the bottom showing an active center pivot system over an alfalfa field in Diamond Valley. A zoomed in view of a sprinkler nozzle spraying the pumped groundwater is shown on the top left.
