Louisville's Clifton air quality reflects the historic Northeast Louisville residential neighbourhood, with vehicle traffic on Frankfort Avenue and the surrounding tree-lined residential and commercial character contributing local sources. The neighbourhood's walkable character and the tree canopy provide natural filtration, while the flat terrain allows reasonable dispersal and Clifton generally maintains moderate Louisville metropolitan readings throughout most of the year.
