[FEATURE REQUEST] ALK4 and R4N2 chemistry from Brewer et al. (2023) #1625

Closed msulprizio closed 2 months ago

msulprizio commented 1 year ago

R4N2 was a common product of alkane, isoprene, and monoterpene oxidation and produced organonitrate SOA but we don’t want ALK4 to produce organonitrate SOA. Jared Brewer has implemented a fix to address this.

@msulprizio, do we have code for this or do we have to manually edit the KPP *.eqn file from the paper?

msulprizio commented 1 year ago

I've emailed Jared to get these code updates. We do not have them yet.

msulprizio commented 5 months ago

@JFBrewer is there any update on this? Could you create a pull request with these updates or point us to your code?

yantosca commented 2 months ago

We can now close this issue as PR #2352 has been merged into the GEOS-Chem 14.5.0 development stream.
