Nonlinear response of ozone to emissions: source apportionment and sensitivity analysis
Cohan, DS; Hakami, A; Hu, Y; Russell, AG
2,005
For secondary air pollutants, precursor emissions may impact concentrations in nonlinear and interdependent manners. We explore the nonlinear responses of one such pollutant, ozone, to emissions of its precursors, nitrogen oxides (NOx) and volatile organic compounds. Modeling is conducted for a high ozone episode in th...
