Unfortunately, I do not have any experience with emissions mapping between cb05e51_ae6_aq and cb6r3_ae7_aq, maybe @barronh does.
For one project, we mapped concentrations from a run with cb05e51 to prepare boundary conditions for a run with cb6r3, and the species we estimated largely line up with the powerpoint you posted. Looking back at that code, we estimated ACET, KET, and PRPA as 0.05xPAR, 0.13xPAR, and 0.014xPAR and then reduced PAR accordingly (also accounting for any differences in carbon numbers). We also subtracted BENZENE from PAR. I think BENZENE had already been included as a SOA precursor species in cb05e51 so we didn’t need to estimate it but for gas phase chemistry purposes its reactivity was still lumped with PAR so we had to subtract it from PAR. The fractions for estimating ACET, KET and PRPA concentrations from PAR were based on some internal analysis by a colleague of ours who has since retired, so unfortunately I cannot provide further documentation. And these concentration-based estimates may not be appropriate for scaling emissions.
The other emissions change you need to be aware of going from ae6 to ae7 concerns biogenic emissions. For ae7, you need to separate APIN from TERP as described in the aero7 overview.
There might be other considerations, but that’s what came to my mind.
