Ozone fumigations that mimic ambient ozone distributions facilitate the development of links between (1) vegetative effects results that are generated in the laboratory and the field and (2) predictive effects models that depend upon ambient air quality data. Experimental exposure profiles were constructed from a readily available ambient air quality data base. Air quality data from selected monitoring sites were characterized over the 5-month growing season by identifying (a) the number of occurrences of hourly ozone concentrations equal to or above 0.07 ppm, (b) the number of days of each episode, (c) the number of days between episodes and (d) the rate of rise and decline of the daily ozone concentrations.
