Short summary
We measured spatial differences in airborne particulate matter (PM) in Oakland, CA, with repeated mobile measurements on all city streets. In addition to primary, we also find higher secondary organic PM downtown, which suggests stronger photochemical PM production in areas of high emissions and poor air ventilation (i.e., urban street canyons). This finding is original because while other modeling studies have predicted higher photochemistry in street canyons, we confirm this observationally.
