Calculates the net solar or shortwave radiation using the "FAO" Penman Monteith approach for reference evapotranspiration (Allen et al., 1998, Equation 38), the "McJannet" approach for lake temperature (McMahon et al., 2013, Equation S11.25), or the McJannet approach for "wet_bulb" temperature (McMahon et al., 2013, Equation S11.31).
1 |
type |
type of net radiation function to use. Defaults to "FAO" for FAO Penman-Monteith reference evapotranspiration. Other options include "McJannet" for net radiation at lake temperature and "wet_bulb" for net radiation at wet-bulb temperature. |
loc |
a list with location information that includes:
|
lake |
A list with lake data. Defaults to NULL, but for McJannet lake evaporation calculations, should include:
|
weather |
a list with weather data that includes:
|
albedo |
a list with albedos for different surfaces, defaults to:
|
Rn |
net radiation (MJ/m^2/timestep) |
