What are required variables in wrfout file for wrf-python run

[Linh Tran]

Hi everyone, I have limited the variables in the wrfout files to reduce the size, however  when I used wrf-python to plot sea level pressure field, an error message was informed as below

"Traceback (most recent call last):
  File "2pwrfout_slp.py", line 82, in <module>
    slp = getvar(ncfile, "slp",timeidx=desired_time_index)
  File "/g/data3/hh5/public/apps/miniconda3/envs/analysis3-19.04/lib/python3.6/site-packages/wrf/routines.py", line
    meta, _key, **kwargs)

    result = wrapped(*new_args)

    result = wrfin.variables[varname][timeidx, :]
KeyError: 'QVAPOR'
"

Actually, there is no QVAPOR in my wrfout files. I would like to ask how to know all required variables in the output file of WRF to let wrf-python run successfully.  Any suggestion is much appreciated!

I could use the answer to this question too.
