Creating a local emission inventory for WRF CHEM

[Rupa]

Hello, everyone. Thank you for allowing me to join this group.

I have been reading the WRF emissions guide, and I want  to be able to use my own emissions inventory in a 1km * 1 km domain.

I am confused as to the approach I should t  take to be able to feed my data into  WRF-CHEM:

a) Should I have emissions of species in the format like EDGAR, RETRO, and simply use prep chem src (Simple text files with latitude and longitude)?

b) Or the NEI emission inventory which I found to be rather complicated (lat-long in one folder and emissions in the other, and some other fortran files were in there too - downloaded from ftp server 'emissions_data_2005')? Also the emiss_v03. F doesn't seem t

o be applicable for domain sizes less than 12 km.

Has anyone ever tried inserting custom emissions data into WRF-CHEM? It would be great if you could guide me.  Thanks.

Sincerely,

Rupa.

Hello Rupa

you might want to check out the anthro_emis and EPA_anthro_emis tools we provide on our website whether you can adapt those for your needs: 

https://www2.acom.ucar.edu/wrf-chem/wrf-chem-tools-community

We cannot help you with emiss_v03. F or prep_chem_src since these tools have not been developed by our team.
