San Diego's Balboa Park Museums air quality benefits from the 1,200-acre elevated mesa park's substantial tree canopy providing exceptional natural filtration. Vehicle traffic on El Prado and the surrounding visitor traffic contribute local sources, while the Pacific sea breeze and the park's elevated mesa position generally maintain the Balboa Park museum campus among San Diego's more moderately ventilated major cultural institutions throughout most of the year.
