The purpose of this paper is to describe a state-of-the-art gas phase chemical mechanism for use in the EPA/NCAR regional acid deposition model (RADM). The Eulerian regional acid deposition model under development at the National Center for Atmospheric Research will require on the order of tens of thousands of grid cells. The gas phase chemical mechanism must have enough chemical detail to give accurate oxidation rates of sulfur dioxide and nitrogen species. It is also important for the mechanism to give accurate production rates of those species such as hydrogen peroxide, organic peroxides and ozone which are necessary for the oxidation of sulfur dioxide in liquid phase. The mechanism must provide this high level of chemical realism while using a minimum of chemical detail.
