Here we document mainly updates. This info will be introduced to the readthedocs side also, though integrated into the text.
GenChem was originally developed when the EMEP CTM used the so-called SNAP emission sector system, which has 11 source categories. The EMEP model currently uses a 19-sector system we refer to as GNFR_CAMS. To produce EMEP-ready files with GenChem one now needs to specify "-g" in the call to emep_setup.py, e.g.
./emep_setup.py EmChem19a-vbs -g
Omission of this -g flag simply gives the 11-sector SNAP splits, though this option is now deprecated.
In each base and extra_mechanisms directory there should now be an emissplit file for whichever sector scheme the user wants. For example, chem/inputs has directories for default splits for both systems, and in e.g. EmChem19a there are now files for both:
EmChem19a_emissplit_gnfr_defaults_voc.csv
EmChem19a_emissplit_snap_defaults_voc.csv
Any new schemes (e.g. in extra_mechanisms) must also have whichever file is needed. Preferably both.
