Hartford's South Green air quality reflects the historic downtown Hartford neighbourhood, with vehicle traffic on the surrounding Main Street and Capitol Avenue corridors contributing local sources. The Bushnell Park's proximity provides limited natural buffering, while the flat terrain allows reasonable dispersal and South Green generally maintains moderate Hartford downtown metropolitan readings throughout most of the year.
