Chattanooga's Southside air quality reflects the historic South Chattanooga arts and entertainment neighbourhood, with vehicle traffic on the surrounding Main Street corridor contributing local sources. The Tennessee River provides limited ventilation, while the surrounding Lookout Mountain and Signal Mountain ridgelines create topographic enclosure and the walkable arts character generally maintains moderate Chattanooga metropolitan readings throughout most of the year.
