Cleveland's University Circle air quality benefits from the cultural campus greenspace including Cleveland Museum of Art and Case Western Reserve University, with vehicle traffic on Euclid Avenue and the surrounding cultural and academic character contributing local sources. The Rockefeller Park's greenway provides natural filtration, while Lake Erie's lake winds provide background ventilation and University Circle generally maintains moderate Cleveland metropolitan readings throughout most of the year.
