Running the Ozipr Model

The EPA's OZIPR model (Ozone Isopleth Plotting Program, Research Version) was designed to be used primarily for calculating emissions reductions needed to reach the NAAQS for 03. Both DOS-based and Windows versions are available and can be downloaded from the Web site: pecs/download

OZIPR contains two comprehensive chemical mechanisms that use two different approaches to "lumping" organics. The two mechanisms used in these models, the RADM (Regional ^cid Deposition Model) and the Carbon Bond Mechanism (CBM), are discussed in Chapter 16.A.3b and in detail by Stockwell et al. [J. Geophys. Res., 95, 16343 (1990) and /. Geophys. Res., 102, 25847 (1997)] and by Gery et al. [J. Geophys. Res., 94, 12925 (1989)].
