Compset question

[jinmuluo]

Hi,

I am using the cesm3_beta06 version code, and want to know if there is any compset that satisfies the requirements of turning on the CAM-Chem and BGC with nudged wind? By looking at the compset website ( CESM2.2.2 Component Sets Definitions ), I only find that the FCfireHIST has the CAM-Chem and BGC on at the same time, and it simulates the historical wind? So, hope someone can give me some clues on how to search for a possible compset that can be used in my study.

best,

A way to look at the compset aliases is to do the following in a git clone of CESM.

cd cime/scripts
./quuery_config --compsets

Likely there won't be a compset that exactly defines what you want to do, but you can use a compset longname to get closer. You'll have to figure out which flavor of CAM-Chem you want to use. But, for example to see ones with CAM and BGC you can do this.

./query_config --compsets | grep CAM | grep BGC

CAM has different ways to nudge wind to observations.

I'll move this to the CAM-Chem forum so you can get more detailed advice from the CAM angle.

Hi Erik,

Thank you so much for your suggestions, very helpful to me! I found the compset FCfireHIST might be the closest one to my requests. The remaining issue is, can I copy the nudged wind namelist parameters in CaseDocs/atm_in to this compest to change it? Is it all I need to do to use the nudged wind in my FCfireHIST case, and anything I forget to cancel in the FCfireHIST compset to cancel the real wind simulation?


thank you so much

For anyone who wants to follow this thread, this modification doesn't work. CaseDocs/atm_in are updated when ./case.submit, it deletes my modifications in the atm_in.

I think you would want to make your modifications in user_nl_cam, not directly in atm_in.

Hi jinmuluo,
For nudging you don't need to find a composer that has nudging. You can use any compset with active atmosphere and paste your &nudging_nl into your user_nl_cam. Nudging will be on that way.

Thank you, Danny

Do you know if there are any new compsets in the CESM3 beta version in which CAM-Chem and BGC-Crop are turned on? I found FCfireHIST is very expensive to run, and I don't know if I really need the fire component on if I want to study ozone.

Hi keith,

Thank you for you reply, if I want to run the cesm with dynamic BGC-CROP components, I have to choose the compsets with BGC-CROP_CICE, and the
SP_CICE compset means the land model will be forced with satellite phenology, and soil BGC will be off?

Hi Jinmuluo-
I don't think you want to turn on active ocean? So, maybe you don't need a B case.
A good candidate may be FWHIST_BGC, which is HIST_CAM60%WCTS_CLM50%BGC-CROP_CICE%PRES_DOCN%DOM_MOSART_SGLC_SWAV.
Also, if you don't find a predefined compset, maybe you want to directly specify a long name that is similar to FCnudged?
Maybe try something like HIST_CAM60%CT1S_CLM50%BGC-CROP_CICE%PRES_DOCN%DOM_MOSART_SGLC_SWAV?
If you are interested in CAM7/CLM6 physics, maybe try HISTC_CAM70%LT%CT1S_CLM60%BGC-CROP_CICE%PRES_DOCN%DOM_MOSART_SGLC_SWAV.
P.S. The issue is that for CAM7 low top (CAM7%LT) the vertical levels are changed to 58 levels, so you may need to prepare for new nudging files. I think at some point there will be nudging files for the CAM7%LT model, but not soon(?). If you don't want to do that, for now maybe sticking with the CAM6/CLM5 physics is a good idea if you do need to nudge the model towards MERRA-2.
I hope this helps?
Danny
