Longwave radiation of the surface

Calculates emissions of a surface.

rad_lw_out(...)

# S3 method for numeric
rad_lw_out(t_surface, emissivity_surface = 0.95, ...)

# S3 method for weather_station
rad_lw_out(weather_station, emissivity_surface = 0.95, ...)

Arguments

...	Additional parameters passed to later functions.
t_surface	Surface temperature in degrees C.
emissivity_surface	Emissivity of surface. Default is emissivity for short grass.
weather_station	Object of class weather_station.

Value

Emissions in W/m^2.

Details

If a weather_station object is given, the lower air temperature will be used instead of the surface temperature.
