Add zonal mean output capability to simple models.

[brian-eaton]

What is the feature/what would you like to discuss?

With the addition of the phys_grid_ctem module it is now possible to output zonal mean diagnostics when using non-FV dycores. However the functionality has only been added for output from the cam[4-6] and cam_dev physics packages, and not for the simple physics models. It would be useful to have this capability added for simple physics. It just requires the addition of a couple of phys_grid_ctem subroutine calls to src/physics/simple/physpkg.F90, analogous to the current calls in src/physics/cam/physpkg.F90.

Is there anyone in particular you want to be part of this conversation?

No response

Will this change (regression test) answers?

No

Will you be implementing this enhancement yourself?

Any CAM SE can do this
