Questions about CLM_USRDAT resolution

[Maggie Xia]

Dear all,
I am running "--compset SSP126_DATM%GSWP3v1_CLM50%BGC-CROP_SICE_SOCN_MOSART_SGLC_SWAV" with default data for a regional case. I just wonder that since I used the " --res CLM_USRDAT" flag, which files determined the resolution of my output file (09x1.25)? Since the climate forcing are at 0.5x0.5, I believe it's domain or surfdata?
That is to say, if I want to run the model at 0.1 degree resolution, what file shall I modify?

I think you would need to:
1. Point to your new surface dataset in user_nl_clm
2. Change the following in env_run.xml: "ATM_DOMAIN_FILE", "ATM_DOMAIN_PATH", "LND_DOMAIN_FILE", "LND_DOMAIN_PATH" to point to your new domain file.
3. You'll probably have to adjust env_mach_pes.xml appropriately for your regional grid (an efficient number of processors).
