Description

sat_vap determines the saturation vapor pressure, e_{s} (kPa), for a given atmospheric temperature.

Usage

1
sat_vap(Ta)

Arguments

Ta

Air temperature, T_{a} (C).

Details

Saturation vapor pressure is determine by (Allen et al. 1998):

e_{s} = \frac{0.611 e^{(T_{a} 17.3)}}{T_{a} + 237.3}
