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 http //www.academicpress.com/ 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 Acid 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 J. Geophys. Res., 102, 25847 (1997)] and by Gery et al. [J. Geophys. Res., 94, 12925 (1989)]. 

The input file for Example 1, exl.inp, has associated with it the RADM mechanism, called meccm.rad and a set of actinic fluxes as a function of solar zenith angles stored as zen.rad. A copy of the RADM chemical species list is found in Table 16.1. 

The input file for Example 8 is ex8.inp and has the associated mechanism meccm.cb4, actinic fluxes as zen.cb4 and reac.cb4. CB4 (or CBIV) stands for carbon bond mechanism, version 4. A species list is found in Table 16.2.
