ERROR: component_mod:check_fields NaN found in ATM instance: 1 field Sa_u 1d global index: 141

Dear scientists of NCAR

I use the CMFD as forcing data to drive CLM5.0, and datamode = "CLMNCEP". Since the CMFD only mask China region, I use this mask to remove the outside region of surface data. However, when I submit the case, it error with the information as follow:

ERROR: component_mod:check_fields NaN found in ATM instance: 1 field Sa_u 1d global index: 141
ERROR: component_mod:check_fields NaN found in ATM instance: 1 field Sa_u 1d global index: 561

ERROR: component_mod:check_fields NaN found in ATM instance: 1 field Sa_u 1d global index: 3501

Could you guide this question?

I will appreciate any help from you. Thanks in advance.
Best regards,

The Sa_u field is wind, so there likely is a NaN in your wind forcing (TPQWL files) at some gridcell.
See, for example, this post:

CLM5.0 ERROR: component_mod:check_fields NaN found in ATM instance: 1 field Sa_u 1d global index: 398.

Dear staff, I only run CLM5.0 and build it successfully. However, when I ./case.submit, error in cesm.log shows； ERROR: component_mod:check_fields NaN found in ATM instance: 1 field Sa_u 1d global index: 398. The atmospheric forcing dataset I'm using is CLDAS, and using ‘CLMGSWP3v1’...
