Leaf to air water vapour pressure deficit calculation
Description
This function calculates the leaf water pressure deficit (VPDleaf or Ds) using the temperature of the leaf, the temperature of the air and its relative humidity. The saturation vapor pressure of water is approximated usung the Tetens 1930 equation.
Usage
f.ds(Tleaf, Tair, RH)
Arguments
Tleaf
Temperature of the leaf in Kelvin.
Tair
Temperature of the air in Kelvin.
RH
Humidity of the air (0 to 100).
Value
Ds in Pascal
References

Examples
f.ds(Tleaf=273.16 + 30, Tair=273.16+28, RH=70)
