Rochester's Upper Monroe air quality reflects the historic residential corridor, with vehicle traffic on Monroe Avenue and the surrounding tree-lined residential and commercial character contributing local sources. The neighbourhood's mature tree canopy provides natural filtration, while Lake Ontario's lake winds provide background ventilation and Upper Monroe generally maintains among Rochester's more pleasant inner residential corridor environments throughout most of the year.
