Description
Get vapor pressure from RHmean and temperature
Usage
1
get_ea_from_RHmean(RHmean, Tmax_C, Tmin_C)
Arguments
RHmean
Mean relative humidity, pct (0-100)
Tmax_C
Max daily temperature, deg C
Tmin_C
Min daily temperature, deg C
Details
Calculate the actual vapor pressure from mean relative humidity and
max and min daily temperature. The calculation is as:
ea = RHmean / 100 * (es(Tmax_C) + es(Tmin_C)) / 2 (FAO 56 Eq. 19)
es(T) is the saturation vapor pressure at that temperature. The function
get_es(T_C) is used for saturation vapor pressure.
Examples
1
get_ea_from_RHmean(RHmean = 68, Tmax_C = 25, Tmin_C = 18)
