Question about changing aerosol emissions

[155066882@qq_com]

Dear all
I want to change the aerosol emissions for mam3 and mam7 simulation.
I know the original files are in atm/cam/chem/trop_mozart_aero/emis/, and the namelist file is in cesm/models/atm/cam/bld/namelist_files/namelist_defaults_cam.xml.
But I can't find the location where the cesm f90 program read and store the emission files, so I can't change them.

Thank you.

It looks like the emission files are read by mo_srf_emissions.F90.

I'm not sure why you need to look at or modify the code in order to change the emissions. In most cases the way to do this would be to modify the existing datasets and then modify the namelist input to specify the modified datasets. By starting from the existing datasets you have a template file that contains all the information that the code that reads the files is expecting. All you need to do is to modify the actual values of the emissions.
