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?

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

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 as discusses in #1625.
A fix from Jared Brewer is included here.

NOTE: The KPP fullchem mechanism has not been rebuilt with these fixes to
facilitate merging these updates up to the latest GEOS-Chem release. These
updates will also need to be added to the custom.eqn file.
