Calculate the outgoing longwave radiation.

Usage

calc_longwave_radiation(
  temp,
  act_vapor_pressure,
  radiation_fraction,
  tmin = NULL,
  tmax = NULL
)

temp: The air temperature in degrees C.
act_vapor_pressure: The actual vapor pressure. Can be calculated with calc_act_vapor_pressure.
radiation_fraction: The fraction of radiation relative to clear sky. Can be calculated with calc_radiation_fraction.
tmin: The daily minimum temperature. Defaults to NULL. If specified with tmax, they are used in place of temp.
tmax: The daily maximum temperature. Defaults to NULL. If specified with tmin, they are used in place of temp.

The outgoing longwave radiation in MJ m^-2 day^-1.
