Systematic airborne measurements of ozone in the smoke plumes from the prescribed burning of forests demonstrate the extent to which ozone is generated by photochemical reactions. The ozone concentration in the upper layer of the smoke plume may exceed the Air Quality Standard of 80 ppb, but a simple diffusion model shows that the ozone concentration at ground level is only marginally affected except under special meteorological conditions. Measurements of the olefins and nitrogen oxides in smoke show conclusively that the olefin content of smoke is not sufficient to account for the ozone produced. The identify of the photoreactive hydrocarbon in the smoke is as yet unknown. 12 references, 5 tables.
