pis the density of water (mass/volume) = 1 g/cm?
Le is the latent heat of vaporization evaluated at the temperature of the air (energy/mass)
Le = 597.3 – 0.57* T (°C)
Q, is the net radiation absorbed (energy/area-time)
E, is the "drying power of the air" as an energy flux (energy/area-time)
E, = pLe (a + bu)(e, – ea)
a + bu is empirical transfer constants in length per pressure time
e, is the saturation vapor pressure at temperature in the air (pressure)
