The report presents a survey of an air quality data base that was collected in Atlanta, Georgia during July and August 1990. In that period, data were collected continuously at six sites and were recorded as 1-hour averages. Data include concentrations of nitrogen oxides, carbon monoxide, ozone, total non-methane hydrocarbon, and 47 identified species of hydrocarbon. Supporting meteorological data were also recorded. The report contains extensive graphical representations of the data including: (1) mean diurnal curves for all gaseous pollutants and (2) plots of pollutant characteristics by wind direction. The automated gas chromatography (GC) systems used in the field in Atlanta produced erroneously high isopentane readings at five of the six sites; the problem appeared frequently and in a severe form at two of the sites.
