WebAbstract Increasing vapor pressure deficit (VPD) increases atmospheric demand for water. While increased evapotranspiration (ET) in response to increased atmospheric demand seems intuitive, plants are capable of reducing ET in response to increased VPD by closing their stomata. We examine which effect dominates the response to increasing VPD ... WebThe Clausius-Clapeyron equation (Iribarne and Godson, 1981, Bolton, 1980) indicates that the saturated water vapor pressure will rise by roughly 7 % for each degree Kelvin of temperature increase in the atmosphere. If the rise in saturated vapor pressure does not match to an increase in actual atmospheric water vapor concentration, the VPD will ...
