Internal function to calculate the PET
Description
the function is an implementation of the FAO 56 standard for evapotranspiration calculation
Usage
PET(latitude, altitude, humidity, temperature, windspeed, sun, sun.mode, date)
Arguments
latitude
self explanatory
altitude
altitude (meters)
humidity
(percent)
temperature
(C)
windspeed
in m/s
sun
radiation, (MJ m^-2 day-1) sunlight (0 to 1) or cloudiness (0 to 1)
sun.mode
how sun energy is calculated (Rsolar = radiation energy, sunlight or cloudiness)
date
a date vector
Value
A data frame of 2 variables: date,PET.
