Knoxville's Old City air quality reflects the historic entertainment and arts district adjacent to downtown, with vehicle traffic on the surrounding Jackson Avenue and Central Street corridors contributing local sources. The Tennessee River valley's enclosure creates seasonal inversion episodes, while the neighbourhood's walkable arts character and the flat terrain allow reasonable dispersal and Old City generally maintains moderate Knoxville downtown readings throughout most of the year.
