Tucson's Menlo Park air quality reflects the historic West Side residential neighbourhood, with vehicle traffic on the surrounding arterials and the nearby I-10 expressway contributing elevated diesel NOₓ. The expressway's proximity and the surrounding West Tucson industrial legacy maintain moderate to above-average readings, while the flat terrain allows some dispersal and the community's residential character coexists with the significant expressway air quality influence throughout the year.
