WebThe water vapor difference in pressure between saturated and actual pressures is represented by the VPD value (Rawson, 1977). The 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.
