Abstract

Tropospheric ozone, a key component of photochemical smog, is a significant hazard to biological systems. Ozone is of particular concern in highly populated urban regions where large numbers of people may be exposed to unsafe concentrations, resulting in impaired respiratory function and an increased risk of heart disease. This article explores the spatial-temporal distribution of tropospheric ozone within the Carolina Piedmont megapolitan area over the ten-year period 1998 - 2007. Analyzing both the spatial distribution and temporal trends of tropospheric ozone levels at this scale is particularly useful for understanding how large urban agglomerations influence regional air quality through the "sharing" of air pollution. The influence of various localized variables known to affect the surface concentration and distribution of ozone, including climatic conditions and the emission of point and non-point precursor chemicals, were also investigated
