This disk contains the programs and input data needed to run the OZIPR model
for estimating the secondary production of the three target HAPs (formaldehyde,
acetaldehyde, and acrolein) for ten study areas (Atlanta, Boston, Chicago, Denver,
Houston, Los Angeles, Phoenix, Pittsburgh, Seattle, and Washington, D.C.).

The function and composition of the individual files are explained in detail in
the full report. Specifically, the interested user is referred to Appendix A.   

To use these programs, first create a folder 'ozipr' on your C: drive and copy 
the 'ozinput' from this disk into C:\ozipr.  (If the target is not on the C: drive, then 
the first line of each of the ten batch jobs needs to be modified to indicate the 
correct drive letter).  Also create a folder named 'ozout' in C:\ozipr, to contain 
the output files from the model runs.  This will be empty until the batch 
jobs are run.

Use Explorer to open the C:\ozipr\ozinput folder.  It should contain eight other 
folders (aloft, bouninit, calcinit, emis, init, inp, met, reac) and 14 other files.  
Ten of these other files have the extension .BAT, and are batch jobs designed 
for specific study areas.  Thus, OZATL.BAT runs all 48 OZIPR  model runs for 
the Atlanta study area, and OZBOS.BAT does the same for Boston, etc.  To run
a batch job, simply double click on it in Explorer.  A study area should take 
about one minute or so to complete (all 48 runs).

After the batch job has run, the output files can be found in the C:\ozipr\ozout
folder.  This will contain 53 files per study area; 48 of these are the individual 
model runs, and the rest are summaries.  The 48 runs represent 3 runs per season
(differing in meteorology), 4 seasons, for either urban or rural counties, either
with or without primary carbonyl emissions.  The file name indicates the 
particular combination for that run - the first three letters indicate the study area,
the next two give the season (wi, sp, su, or au), then a single digit (1,2, or 3) for 
the meteorological data used, then 'u' for urban or 'r' for rural, and finally 'c' for 
carbonyl emissions or 'n' for no carbonyl emissions.

(Note that though three meteorological scenarios are output for each season here,
a scenario may have been composed from only a small number of days. See the 
full report for these cases.)
  
Four of the summary files are concatenations of the 12 runs per year for a fixed 
choice of (urban/rural) and (carbonyl emissions/no carbonyl emissions).  The final 
output file (named for instance 'ATL.TXT' for Atlanta) contains all 48 output files 
concatenated together.

Each output file contains instantaneous concentrations of the target HAPs at the 
top of each hour from 8 A.M to 8 P.M. (indicated as times 800 and 2000, 
respectively).  Standard time is used, not Daylight Saving Time as indicated on 
the output files.  The maximum concentrations for each pollutant reached during 
the modeling period are indicated at the end of the file.
