I am configuring CMAQ with SAPRC07TB to calculate biogenic emissions inline, and am looking for a GSPRO file with the correct speciation codes. The GSPRO files provided as examples with CMAQ and SMOKE only apply to the carbon bond mechanism, I believe.

Thank you,  
Elyse

Hi Elyse,  
You need the B10SP profile. The gspro distributed with CMAQ should contain it:

Starting with CMAQv5.3, the gspro profile is also determined by your version of aero (e.g. aero6 and aero7 with CB6 make different assumptions about monoterpenes).
