What is the future of drought in the United States?  An important part of answering this question is understanding how atmospheric evaporative demand (E0), “the thirst of the atmosphere”, will change. Evaporative demand, also referred to as potential evapotranspiration, can lead to drought stress on a landscape and increase irrigation needs for agricultural systems.  The authors address whether currently used formulations for determining E0 are up to the task of projecting drought in the future.
