-*the JPL kinetics package includes a lot of fixes to C & N conservation, but it won't *fully* solve the problem; there are three sets of reactions that still have some issues:
-- aerosol formation reactions, because some of the lumping of species there allows compounds with different C# to form the same particle-phase lumped compounds; the aerosol reactions tend to favor N conservation over C conservation. We'd have to add (at least one) more particle-phase carbon-carrying compound(s) to fix this.
-- (H)CFC and other halocarbon oxidation reactions, which make halogen radicals but not carbon. We could easily fix this by sending all the carbon to CO2, but it barely makes a difference and I'm not entirely sure that's what they do... but I couldn't find easy literature to cite on that front. Our current reactions for those are simplified to one-step processes, e.g. OH + CHCl3 = 3.000Cl + HO2, so I do think it'd be fine to just add CO2 (or CO?) with them.
-- terpene nitrate reactions, which Jessica Haskins was working on for years now but doesn't like it sound has gone / is going anywhere. The terpene scheme that I came up with late last year would fix this, but I haven't yet taken that to the writeup stage... I met with Jessica last week and she's willing to give me access to her compiled field data for comparison, so I'm hopeful I can get to that soon.
