Abstract Knowledge of the complex interactions characterizing the photochemistry of tropospheric ozone production has significantly increased in the past but there exists no clear scientific consensus on the best strategy for reducing ozone. The role of volatile organic compounds and oxides of nitrogen in the production of tropospheric ozone has long been recognized. Elevated tropospheric ozone levels have proven to be much more difficult to control than other pollutants that have shared the focus of recent control efforts. Because of the nonlinearities in the relationships between ozone and its precursor species, it is not at all simple to prescribe the requisite precursor emission reductions necessary to reduce ozone concentrations to a given level. Sensitivity analysis of emitted species will provide important insights for emissions control strategies for reducing ozone. We will present a preliminary result of sensitivity analysis in the emission control process by using an automatic differentiation technique.
