How to get RO2 concentration in saprc

CMAQ

Hi guys,

I’m wondering how to get RO2 conc. in models.cm3 by using saprc mech.
I know RO2 is straightforward in cb mech, but I cannot find the total peroxy radical concentration in saprc mech.

How can I calculate it? And the Molecular Weigh in saprc mech is same to the cb mech?

Thanks!!!

SPARC does not have any single species for total RO2. You will need to add all individual RO2 species to obtain total RO2 in SAPRC. MW in CB and SAPRC will be different. You can find MW in GC*.nml.
Thanks!
