Phoenix's Grand Avenue air quality reflects the historic diagonal commercial corridor, with vehicle traffic on Grand Avenue and the surrounding mixed industrial and arts character contributing local sources. The flat desert terrain allows reasonable dispersal, while the industrial conversion character and the downtown proximity maintain moderate to above-average Phoenix metropolitan readings and the Grand Avenue corridor generally tracks at typical inner Phoenix industrial-creative transition levels throughout the year.
