Class Documentation

class Walcek_cloud : public module_base

Calculates a cloud fraction using 700mvb RH. Extrapolates RH@700mb via Kunkel (1989).

Depends:

• Air temperature “t” [ \( {}^\circ C \) ]

• Relative humidity “rh” [%]

Provides:

• Atmospheric transmittance “cloud_frac” [0,1]

~Walcek_cloud()

virtual void run(mesh_elem &face)

Needs to be implemented by each data parallel module. This will be called and executed for each timestep

Parameters:

• face – The terrain element (triangle) to be worked upon for an element parallel domain

• global_param – A pointer to the shared global paramter space with domain-wide paramters
