Description
Computes and adds E0, ES0, ET0 to a WeatherObject where these are absent
using Penmans formulation.
Usage
1
Penman(w)
Arguments
w
WeatherObject where E0, ES0 and ET0 are not computed yet.
Details
This routine calculates the potential evapo(transpi)ration rates
from a free water surface (E0), a bare soil surface (ES0), and a crop canopy
(ET0) in mm/d. For these calculations the analysis by Penman is followed
(Frere and Popov, 1979;Penman, 1948, 1956, and 1963).
Value
WeatherObject w with added E0, ES0 and ET0 slots.
Examples

w <- randomWeather
w@E0 = NULL
w@ES0 = NULL
w@ET0 = NULL
w <- Penman(w)
