Three chemical kinetics mechanisms (Carbon Bond II, lumped species mechanism used in Demerjian and Schere's photochemical box model and the Cal Tech mechanism developed by McRae) were used in a modified version of the OZIPP model to replicate smog chamber data in which automotive exhaust was irradiated (Bureau of Mines data). Two of the mechanisms (CBII and Demerjian) agreed with the data, as well as the existing mechanism in OZIPP (Dodge propylene/butane). The OZIPP model was next used to simulate several days of observations made during the St. Louis RAPS. In several cases, it was found that the meteorological input and/or assumptions did not allow an adequate basis to compare the mechanisms. Three days in which the meteorological input appeared appropriate were simulated using OZIPP with the Dodge, Demerjian and CBII mechanisms. Differing peak ozone and control estimates were obtained, depending on the day simulated and choice of mechanism. Sensitivity tests were employed to explore observed differences among the mechanisms tested.
