Abstract
This report describes an air quality and meteorological monitoring program conducted at nine sites in southern Louisiana from July through October 1976. The objective of this monitoring program was to provide air quality data applicable to non-urban portions of southern Louisiana and to perform a limited analysis of the data gathered. It was found that the frequency of observations exceeding the 80 ppb standard for ozone at the nine sites ranged from four to seventeen percent of available observation with ten percent of the total number of observations exceeding a concentration of 80 ppb. Five percent of the total ozone observations exceeded a concentration of 100 ppb. The diurnal oxidant pattern at each of the sites is similar to patterns typically found in urban areas. It was not possible to ascertain the cause of the high ozone measurements, but examination of upper air trajectories for periods of high ozone concentrations shows that local urban sources are important contributors. Overall the NO2 and SO2 levels at all of the monitoring sites was very low. No concentrations of these pollutants in excess of air quality standard values were observed.
