Psychrometric constant
text:
The psychrometric constant γ relates the partial pressure of water in air to the air temperature. This lets one interpolate actual vapor pressure from paired dry and wet thermometer bulb temperature readings. Both λ v and M W r a t i o are constants.
Since atmospheric pressure, P, depends upon altitude, so does γ .
At higher altitude water evaporates and boils at lower temperature. Although H 2 O is constant, varied air composition results in varied a i r . Thus on average, at a given location o
