I am trying to run a case with only biogenic emissions using CMAQ5.2.1.
We generate biogenic emissions using MEGAN3.0, which include many gas-phase species, but no aerosol species.
This seems to be a problem, because I get the error shown below.
Value for CTM_ZERO_PCSOA not defined;returning default: FALSE >>--->> WARNING in subroutine AERO_EMIS_INIT on PE 014 Cannot define index for SO4 emissions: aerospc%emis=' ' in AERO_DATA.F.

Is it possible to run CMAQ 5.2.1 without aerosol species? I have set the flag “setenv CTM_EMISCHK F” to bypass the check in the emissions.
