Add fixes for ALK4 and R4N2 chemistry from Brewer et al. (2023, JGR)
Browse files Browse the repository at this point in the history 
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.
