Abstract
The basic design of the EPA's Regional Oxidant Model (ROM) is described and preliminary results are presented of a study of the impact of biogenic hydrocarbon emissions on ozone concentrations in the North-eastern United States. It is shown that the predicted maximum ozone levels during a six day period in July 1980 agree better with observed concentrations when the biogenic component is included in the hydrocarbons emissions than when it is omitted. The largest effects of the biogenic hydrocarbons occur in the Appalachians, downwind of large NOx sources in the Ohio River, where peak 1-hour averaged concentrations over the six-day period drop by as much as 50 ppb when the biogenic emissions are shut off.
