I have already used GOCART aerosol option, but some WARNINGs still apprear.

[cxyiyh]

Hi, enthusiastic friends:
when I ran ./wrf.exe, it showed some WARNING:
WARNING: dust option 1 currently works only with the GOCART aerosol option.
WARNING: sea salt option 1 currently works only with the GOCART aerosol option.
but I have already used GOCART aerosol option, and I set chem_opt = 301.
Why did those WARNINGs apprear?Thank you for your reply.

Hi cxyiyh,

Take a look at chem/chemics_init.F:

if ( config_flags%dust_opt == 1 ) then
call wrf_message("WARNING: dust option 1 currently works only with the GOCART aerosol option.")
endif

this is just a standard warning whenever this dust option is selected, no matter the chem_opt.
