What does "wt_nat_patch" point to?

[LiwenWu]

Dear Scientists,
I was running a I2000Clm50SpGs case for spinning up, but after submitting the case, an error occured:

I opened the cesm.logfile and it showed:

I attached the cesm.log file behind. I wonder what is the meaning of wt_nat_patch? Does it point to the third subgrid level -- patch level mentioned in the CLM Technical Note? Could you please give me some advice about this error? Noted that I have changed the land use, PFT, LAI and soil texture data in the surfdata file.
Any advice would be greatly appreciated. Thank you.

Yes, it is the third subgrid level - patch level. Since you are using a custom surface dataset, it probably means that the sum of your plant functional types are not adding up to 100% in each gridcell, rather the sum seems to be greater than 100%.
