run scripts LUMIP simulations

Hey all

I would like to inquire about the possibility of getting some of the run scripts used for the LUMIP simulations, more specifically for hist-noLu experiment.
I am a starting Phd student who will be using CESM 2.1.2 within the framework of a European project, the simulations we will do are roughly based on these LUMIP simulations,
as I have never worked with CESM before I am rather unfamilliar with how to construct such a run script. Is there a possibility that you would share one of these scripts with me?
I already checked the page with CESM experiments from which I could get the namelist files which is already a great help, however I couldn't find any run scripts.

Thank you for the info!
Cheers
Steven

If you haven't done this yet, you would need to download CESM (and port it to your machine if necessary).
Then follow the quick start guide to setup, build and run the case.
You can mimic the case you want by looking at the caseroot files link for that specific case at:

You would want to create your case according to the information in the README.case file.
Let us know if this is not the type of information you were looking for.

Hi, thanks for the quick response!

I have been doing the porting and the testing to verify this and I have already constructed a script based on the quick start guide.
However I have the feeling that, as a novice user, I would probably approach the writing of this run script in a different way than a more experienced user, that's why I requested an example run script, both to be certain that I am doing the right things (which I can indeed verify as well through the case files), but also to see the structure of the writing of the run script.

Are these scripts saved somewhere and openly available? Or is the idea that all users should construct there run scripts independently on the basis of the case files?

Cheers
Steven

All of the CESM2 CMIP6 simulations (including the hist-noLU simulation) were run using the workflow engine "Cylc" (https://cylc.github.io/cylc/). Cylc took care of running the model, processing the data into timeseries and CMIP6 format, and running diagnostics. However, the implementation of Cylc for these simulations is not available/supported outside of NCAR.
You can run the model by simply using the case.submit script in the case directory and the resubmit capability (using RESUBMIT in env_run.xml in the case directory).
