All, for the information on how MOVES does speciation, some more details are available here:
Speciation of Total Organic Gas and Particulate Matter Emissions from
On-road Vehicles in MOVES2014b (PDF)
Speciation Profiles and Toxic Emission Factors for Nonroad Engines
in MOVES2014b (PDF)
And CARB also has its own speciation database:
If you are trying to do your own speciation, t hat will require some additional inputs that are not part of the standard platform. I think the closest thing we’ve posted to date
for that is this package:
That package is designed for running SAPRC speciation for onroad, but can be used more generally to apply a non-MOVES speciation within SMOKE-MOVES via traditional speciation
profiles. If you is planning to use the Speciate Tool to generate new profiles for use in SMOKE-MOVES, you need to generate integrate profiles that incorporate all of the MOVES integrate HAPs (styrene, hexane, ethylbenzene, etc). It has the potential to get
complicated… One option is to forego SMOKE-MOVES completely and run the onroad FF10 through SMOKE, which would make speciation a bit simpler; If that is the direction you might want to go, we can provide some more info on that.
For nonroad, there are nonroad SCCs in the standard platform GSREF, and that is how we speciate nonroad emissions in California. Some of these SCCs use the GSPRO_COMBO. For
Speciating nonroad emissions in California using regular criterial speciation profiles applied to EXH__VOC and EVP__VOC should be fairly straightforward. As for the rest of
the country, that gets more complicated because assignment of speciation profiles is determined by MOVES via the NONHAPTOG splits (NONHAPTOG8869, NONHAPTOG8775, etc).
