Described are new methods for dispensing and monitoring ozone in open top field chambers; such chambers are used in studies of the effects of oxidants on plants. One system semi-automatically dispenses and automatically monitors ozone in multiple open top field chambers at distances as far as 106 m. Effects of the chambers on air velocity, light, temperature, ozone distribution, and plant growth are determined. Various gaseous pollutants could be monitored with minor modifications to the system. Although open top chambers affect the plant environment, the effects are fewer than those induced in closed chamber designs. (4 diagrams, 17 references, 5 tables)
