Abstract: Chemical measurements made during an air pollution event in Atlanta, GA have been compared with results from several photochemical simulations. Measurements included O 3 , primary reactive organic gases (ROG), aldehydes, PAN, total reactive nitrogen (NO y ) and H 2 O 2 , with vertical profiles for primary ROG. Photochemical models using two different chemical representations and a range of assumptions about winds, vertical mixing and emissions were used to simulate the event. Results show that assumptions about vertical mixing can cause a variation in simulated surface concentrations of primary hydrocarbons of a factor of two or more. A tendency to underestimate isoprene was found in comparison with measured vertical profiles. The models tend to overestimate concentrations of HCHO, H202 and PAN in comparison with measurements. Peak O 3 and concurrent NO y from helicopter measurements was used as a basis for evaluating individual model scenarios. Scenarios were developed with different O3 NOx- ROG sensitivity, but only the NO x - sensitive scenarios are consistent with measured O 3 , NO y and isoprene. [ABSTRACT FROM AUTHOR]
