Vertical Allocation of CMAQ emissions

Hi all,

I’m converting CMAQ-ready-to-use emission files to wrfchemi* files. I have 34 layers for my WRF/Chem emission, but there’s only 1 layer in the CMAQ emission. I think I need to do vertical allocation for them, but just don’t know how to do that. Does anyone have advice for me? I’ll highly appreciate that!

Do you have both gridded and point source emission files that you are trying to use? If you have point source files with stack information then we do not have a tool for recomputing plume rise in WRF-CHEM.
