However, they turn out to have little effect on results at highly dilute vapour concentrations.
2.
Vapour concentrations of 1, 000 ppm cause marked irritation of eyes, nose and upper respiratory tract and cannot be tolerated.
3.
The range of temperatures and water vapour concentrations over which the optical depth computations are valid depends on the training datasets which were used.
4.
Transpiration rate is differential water vapour concentration, mbar, multiplied by the flow of air into leaf chamber per square meter of leaf area, mol s " 1 m " 2, divided by atmospheric pressure, in mBar.
