As defined in the AMS glossary, a parameterization is a simplification of one or several processes in a model. I add that a parameterization commonly adds an error and increases the uncertainty in the model results. In most cases, a parameterization is not derived from physical laws but a fit to data. These simplifications are employed for different reasons....

I could run model, i just had to change a bit the namelist. I added three parameters:io_form_auxinput5 = 2,auxinput5_inname = 'wrfchemi_d$<domain>$_$<date>$' and frames_per_auxinput5 = 168. (168 hours of emissions and hours of simulation) &time_control run_days = 0, run_hours ...

I would suggest using cdo for your purpose. At least for variables, which values are independent of the grid cell size, one can use cdo. cdo cdo (Climate Data Operators) is a command line program to process netCDF and GRIB files. It is developed an maintained by Uwe Schulzweida and colleagues at the Max-Planck Institute for Meteorology in Hamburg, Germany. ...

Did you use the right Vtable? That error message is saying that the soil temperature variable is missing/couldn't be read.

Spatial reference systems are coordinate systems that can be geographical coordinate systems defined on a model ellipsoid or projection coordinate systems. A projection coordinate system is defined by four groups of parameters: model ellipsoid, projection type projection parameters measurement unit EPSG codes refer to complete spatial reference systems ...
