How to use modified flux data when running an ocean-only model?

[cesm_beginner]

In CESM, the fluxes are calculated in the coupler and are passed to different component. Is it possible to force the CPL to read the flux data from my own dataset? Should I change the code or there are exsited settings?

Any advice on this is appreciated !

This is the purpose of the CESM data models. For an ocean-only configuration, this can be done with the C compset, or G compset if you also want active sea ice:

There are a number of out-of-the-box forcing datasets available. Changing the data models to use your own forcing dataset is possible though can be challenging depending on how closely your dataset matches the necessary format and variables.

If you have specific questions on this, I suggest posting more details to the ocean forum.

Thanks for your kind reply. I appreciate the effort by you outstanding developers. As far as I know, all data models can only provide specific variables to the CPL rather than fluxes. Therefore, only those variables, 10-m wind speed in the DATM for example, can be customised instead of fluxes such as wind stress.

What if I want to use my own fluxes dataset? In this context, CPL is actually deactivated.

Could you please give me some advice on it? I am looking forward to hearing from you!

Thank you for clarifying what you want to do. Unfortunately, I am not aware of a straightforward way to do what you want.
