Sensitivity and Uncertainty of Reaction Mechanisms for Photochemical Air Pollution


A sensitivity/uncertainty analysis is performed on a mechanism describing the chemistry of the polluted troposphere. General features of the photochemical reaction system are outlined together with an assessment of the uncertainties associated with the formulations of mechanistic details and rate data. The combined effects of sensitivity and uncertainty are determined using the Fourier amplitude sensitivity test (FAST) method. The results of this analysis identify the key parameters influencing the chemistry of NO₂, O₃, and PAN. Based on these findings, a series of recommendations are made for future experimental kinetic studies.
