Psychrometric constantThe psychrometric constant, γ = , ralates 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[1].
Additional recommended knowledge
Although is constant, varied air composition results in varied . Thus on average, at a given location or altitude, the psychrometric constant is approximately constant. Still, it is worth remembering that weather impacts both atmospheric pressure and composition. vapor pressure estimationSaturated vapor pressure,
