Hi All, Hope you will be able to advise, I have generated my own gridded emissions files for CMAQ (not using SMOKE) as I needed some very spesific temporal and species profiles applied . I have generated a NetCDF file using the global attributes of the MET_CRO_3D file. When I view these emissions i…

First, see the wrftom3 manual, https://cjcoats.github.io/ioapi/WRFTOM3.html – it is part of the I/O API’s M3Tools package, documented at https://cjcoats.github.io/ioapi/AA.html#tools

One thing I notice immediately is that TFLAG is integer, and the emissions-variables should be float not double. This is likely to cause many sorts of trouble… …and: variable AACD ACE is some sort of naming screw-up; this should be two separate names AACD and ACET; the internal data structures…

Thanks very much for this, I was about to use wrftom3 to generate emissiosn files which are now running fine

Hello，I have met the same questions. Could you please tell me how to use the wrftom3 to solve? Thanks very much

Hi hannah, I had the same problem as you after adding variables to the emission file，How did you solve the problem？when I run CCTM I get the following error: Error reading IDs for variable HF AL netCDF error number -49 processing file “GR_EMIS_001” NetCDF: Variable not found Thank…
