CAM6 code structure documentation

[NiCosentino]

I am looking for documentation on the general code structure for CAM. Ideally a schematic showing main modules and how they interconnect. Could not find it in the scientific guide (CAM5 Scientific Guide — camdoc documentation). I need some understanding of the general code and this would help. Thanks in advance for any help with this!

Hi Nicolas,

Beyond the scientific guide and user's guide, we don't have much documentation for the actual code. If you tell me which version of CAM you are working with, I can give you at least a place to start.

Hi Courtney, thanks. I am working with CAM6

Great.

I recommend starting here: $CAM/src/control/cam_comp.F90.

In here, you can see the run sequence (e.g. when the physics and dycore run). From here, you can work your way down to more granular modules based on what you're interested in by searching for modules (in $CAM/src/) that contain the subroutines you'd like to look at.

Hope that helps!
Courtney
