WebThe vapor pressure deficit, often known as VPD for short, is the difference between the actual vapor pressure of the air and the saturated vapor pressure. This difference may also be written as VPD. Kilopascals are the units that are used to measure it, and it is an indication of how dry the air is in the environment at any one time (kPa).
