Dear All

I want to ask about some variables in the code of Regcm-4.1.1:

the variables (alb) and (albc) in program of mod_radiation.F90 in the Main, are these the total albedo of atmosphere and surface, or the albedo of the atmosphere only for all and clear sky.

Can I calculate the cloud albedo from the difference between alb and albc?

Also, the variable of (solin) in output file of RAD, is the incident solar radiation at the surface or at the top of atmosphere?

thanks in advance.
