How to find the code to caculate surface heat flux(SHFLX) and latent heat flux(LHFLX) in CAM5?

Dear all,
I know the fomular to calculate the latent hear flux and surface heat flux in CAM5 from 'Description of the NCAR CAM5' provided in the web, but I want to make sure the specific calculate process in the model by checking the code. I've been looking for them for a long time but I couldn't find them...... Is anyone know the specific documents to calculate them?

Thank you!
Li

For CAM the surface components provide the upward fluxes from the different surface types (land, ocean, sea-ice, and land-ice) and CAM provides the downward fluxes from the atmosphere. So you need the fluxes from all the components to get this.

As such I think this probably more a question under CESM general which includes the coupler. So I'm going to move it there. I'll leave a redirect though.

Dear Kluzek, thanks for your reply!
Your advice remind me that the surface fluxes calculation process may exist in the Coupler or other models.
Before, I could only find some documents using 'shf or lhf' to calculate something like cloud fraction, PBL, eddy diffusion and so on in CAM, but I can't find specific documemts to calculate shf or lhf themselves. Now, I find some documents in Coupler and the ocean models which I focus on. "shr_flux_mod.F90" & "forcing_shf.F90". I hope I've found the right documents that meet my needs, any other suggestions will be grateful!
