Denver's City Park air quality benefits from the 330-acre Front Range greenspace, with the park's extensive woodland and open meadow providing natural filtration against the surrounding Denver metro pollution. Vehicle traffic on 17th Avenue and the surrounding residential and museum corridor contribute local sources, while the Rocky Mountain westerly airflows on most days provide clean background ventilation and the park generally maintains better conditions than the enclosed Denver downtown street canyons throughout most of the year.
