Not Applicable
If this is a port to a new machine: Please attach any files you added or changed for the machine port (e.g., config_compilers.xml, config_machines.xml, and config_batch.xml) and tell us the compiler version you are using on this machine.
Please attach any log files showing error messages or other useful information.

Describe your problem or question:
Hi all,
I'm looking to run some coarse simulations with a slab ocean model where I can vary CO2 concentrations (this seems easy enough to do in user_nl_cam by setting co2vmr equal to my desired concentration) and after spin up add some generic top of atmosphere cooling signal of -1 W/m2 and then see how the atmosphere and ocean react.
I understand from reading several discussion posts and the "SOM FAQ" that dbailey put together that slab ocean runs use DOCN%SOM, and that they require specifying a valid DOCN_SOM_FILENAME for the mixed-layer depth and Q-flux forcing file. I also saw that the E-type compsets are generally used with DOCN%SOM because they include active sea ice.
At the moment I do not yet know the exact configuration my advisor and I will ultimately want, but answering a few foundational questions would help us get started:

At the moment I do not yet know the exact configuration my advisor and I will ultimately want, but answering a few foundational questions would help us get started:
- Is it generally recommended to begin from one of the E compsets (rather than modifying something like F2000climo) when setting up slab ocean experiments?
- Are there recommended SOM forcing files in the inputdata repository that are appropriate for coarse resolutions?
- If we wanted to keep a configuration as close as possible to our previous F2000climo atmospheric setup, would starting from an E-style compset with CAM6 / CLM5 and DOCN%SOM be the best approach?
- Are there any common pitfalls or configuration issues that new users encounter when first setting up slab ocean experiments that we should be aware of?
