Description:
The report presents the results from air quality monitoring program conducted in the Atlanta, Georgia region during July 1981. The study included data collected at several ground sites as well as airborne measurements using an instrumented aircraft. Study participants included Washington State University and Gas Kinetics and Photochemistry Branch, U.S. Environmental Protection Agency, Research Triangle Park, NC. Measurements included ozone, oxides of nitrogen, PAN, individual hydrocarbons (C1 - C10), halocarbons, condensation nuclei, visual distance plus numerous other meteorological parameters. Isoprene and monoterpene emission rates were determined for the most abundant vegetation species in the Atlanta region. Three SF6 tracer release experiments were performed in order to better understand dispersion patterns in the Atlanta area. Some study observations include: (1) The observed 6-9 AM HC/NOx ratio in Atlanta was 8.6 compared to the value of 1.5 estimated from emission inventories, (2) the natural hydrocarbon burden to the total nonmethane concentration ranged from 2 to 7% and (3) ozone predicted by a city specific EKMA treatment agreed well with observed O3 concentrations.
