metgrid.exe error: The mandatory field TT was not found in any input data

[xuelingzhao]

Hi, I successfully run the ungrib and geogrid, but failed at metgrid step. The error message is:

The mandatory field TT was not found in any input data.

Could you help to check how to solve this error? What does TT mean?

Additional information:
ungrib data parameters:
Date range: 202106080000 to 202106110000
Parameter(s):
Geopotential height
Ice temperature
Potential temperature
Pressure
Pressure reduced to MSL
Relative humidity
Snow depth
Soil temperature
Soil type
Temperature
u-component of wind
v-component of wind
Vertical velocity (pressure)

attached namelist.wps, and some other logs that I think may be useful.

Thanks for your help in advance!

Hi,
According to your ungrib.log, it looks like you're only processing SST data. For e.g., this is the only field shown in the log.

Is your 'Vtable' perhaps linked to Vtable.SST, instead of the intended Vtable.*?

Hi, I checked the Vtable link is correct, however my input data seems not to contain all variables we needed. Resolved after downloading all parameters available in NCEP dataset. Thanks!
