Dear all,

I need to set WRF to output the history of the following variables during a GOCART model run (chem_opt=300). The variables are NO2,O3,CO and SULF.

Which lines do I need to modify the in the registry.chem file?

Thanks a lot beforehand,

Hi Joseph

That chemistry option does not simulate O3, NO2, or CO. Take a look at where chem_opt == 300 is defined in Registry/registry.chem and you will see that these species are not listed. If you want to simulate these compounds, you will need to choose a different chemistry option (e.g., 112 or 301).
