We've got the equations below:




 

Ric(t): clear sky hourly (t=hr, MJ m-2 h-1) or daily (t=d, MJ m-2 d-1) ground reflected diffuse irradiance on an inclined surface

Ri(t): hourly (t=hr, MJ m-2 h-1) or daily (t=d, MJ m-2 d-1) ground reflected diffuse irradiance on an inclined surface

Gic(t): clear sky hourly (t=hr, MJ m-2 h-1) or daily (t=d, MJ m-2 d-1) global irradiance on an inclined surface

Gi(t): hourly (t=hr, MJ m-2 h-1) or daily (t=d, MJ m-2 d-1) global irradiance on an inclined surface

r: surface albedo

rR: isotropic ground reflected view factor

(ground reflected diffuse radiation is equal to zero on horizontal surfaces)
