This page is intended to incorporate the latest version of JPL chemical kinetics (June 15, 2011) into GC standard chemistry.
Standard Chemistry
For Consideration
Below is a list of reactions that were updated in the JPL 10-6 document. Note that the temperature sensitivity value, E/R, is entered following JPL format, so the sign is opposite of the GEOS-Chem format.
| Description | A | E/R |
| HO2 + HO2 -> H2O2 + O2 | 3.0e–13 | -460 |
| HO2 + HO2 + M -> H2O2 + O2 | 2.1e-33 | -920 |
| HO2 + HO2 + H2O -> products | 5.4e–11 | 410 |
| HO2 + NO -> NO2 + OH | 3.3e-12 | -270 |
| ISOP + NO3 -> products | 3.3e-12 | 450 |
| ISOP + OH -> products | 3.1e-11 | -350 |
| ISOP + O3 -> products | 1e-14 | 1970 |
| ALD2 + OH -> products | 4.63e-12 | -350 |
| C2H6 + OH -> products | 7.66e-12 | 1020 |
Perhaps we should consider adding O1D + H2 -> OH + H (A=1.2e-10). The reaction rate could be added to the parametrization of O3 photolysis to 2 OH. This reaction is included in other chemical mechanisms (e.g., Carbon Bond 05 and MOZART4).
