Estimating the ozone-forming potential of urban trees and shrubs

A method for estimating the ozone-forming potential of urban trees and shrubs is presented based on daily emission rates (a factor of hourly emission rates and local temperature and light data), biomass factors (a factor of leaf mass and canopy volumes), and maximum incremental reactivities (MIRs) of isoprene and monoterpenes. The method is then applied to 308 species of trees and shrubs common to the California South Coast Air Basin, and the species are ranked according to their ozone-forming potential.
