Abstract |
A sensitivity study was undertaken to assess the effect of selected parameters on the predictions of a photochemical kinetics model. The model was previously developed for use in designing control requirements for ozone reduction in urban areas. The parameters varied in the present study included (1) solar energy, (2) dilution rate, (3) post 9-A.M. emissions, and (4) hydrocarbon composition of 6-9 A.M. emissions. Based on the results of the simulations for each of these parameters, O3 isopleths as a function of initial non-methane hydrocarbon and NOx were constructed. A comparison of the degree of hydrocarbon control predicted to achieve the air quality standard for O3 was made for each set of isopleths. It was found that the predictions of the model are largely insensitive to the parameters investigated when the results of the simulations are interpreted in a relative sense. |
