-*'''''Becky Alexander wrote on 14 Sep 2015:'''''
-:I've incorporated both the metal catalyzed chemistry and the sulfate isotopes into v10. The metal catalyzed chemistry is much slower than it is when run in v8 and v9. I still have not yet figured out why. I'm not comfortable adding this into the standard model until I figure it out. The emissions are quite different in v10 because of HEMCO, and metal catalyzed chemistry is very sensitive to emissions of primary anthropogenic sulfate, so that's my current hypothesis for the difference. I will probably not get back to debugging this until late October.
