Connecting SAPRC07TC POA emission to POC

Hello,

I’m trying to connect SAPRC07TC’s POA emission to CMAQ.
CMAQ has two POA variables, which are POC and PNCOM, and I modified CMAQ_Control_DESID_MECH.nml as below.

Adding
‘EVERYWHERE’, ‘ALL’ ,‘POA’ ,‘APOC’ ,‘FINE’,1. ,‘MASS’,‘a’,

However, when I try to run the CMAQ, it consistently shows that POA emission is an unused variable, which is not connected to the CMAQ.

Is there any method to connect POA to CMAQ POC?

Sincerely,
Ganghan

I found the reason why POA emission conflicts with the newly added POA variable in CMAQ. I changed the CMAQ variable name, and the problem was solved.
