This distribution contains files and programs implementing the SAPRC-99
gas-phase atmospheric chemical mechanisms for use in airshed models for
predicting the effects of VOC and NOx emissions on tropospheric ozone and
other measures of air quality.  See SAPRC99.HTM or the web page below
for details.

The latest versions of these files should be available at
/~carter/SAPRC99.htm.

To install:

1. Create a directory on a disk with at least 40 MB free that will serve
as the "root" subdirectory for the distribution. All files will be
installed in a subdirectory structure below this.

2. Give the command "A:\tmp/INSTALL a:\tmp d:\root", where "A:\tmp" should
be replaced by the designation of the disk and directory where you copied
MODEL.ZIP, INSTALL.BAT, AND PKUNZIP.EXE, and "D:\root" should be replaced
by the designation of the disk and directory that you created in the
previous step. Note that the directory D:/root must already exist; the
install batch file doesn’t create it. If the above instructions were
followed properly, the files should be extracted and be in the directory
structure required for the installed examples to work.

3. If you do not have a license for Lahey F77L/EM or its current
equivalent, then delete all the files that were installed in the LIB
subdirectory. You will be able to run the examples and do chamber and
reactivity calculations using the installed executable files, but you will
not be able to modify the mechanism or any of the programs. If you do not
intend to modify any of the programs, you can also delete the files in the
subdirectories to SOURCE, though you will need to keep SOURCE/INT3.LIB if
you want to modify any of the mechanisms.

4. After it installs the files, the INSTALL.BAT procedure will test to see
if your DOS window has sufficient environment space for the example batch
files and other procedures to run. If it does, you will get a message
saying so. If it doesn’t, look at FIXENV.TXT to see how this can be
addressed for various operating systems. This should not be a problem for
properly configured Windows 95 or higher systems.

5. INSTALL.BAT also creates a file called NEWENV.BAT that sets the
environment variables that are needed to run the examples and compile the
programs and mechanisms. Note that unless you edit NEWENV.BAT as indicated
in comments to that file, running it will over-write your path so other
programs you may not use will no longer work in this DOS window.
NEWENV.BAT called when you run any of the example batch files, and also if
you open the window using WIN95DOS.PIF. Otherwise, you will need to run
this manually in order for the programs to work.

6. Run EXAMPLE.BAT to run the examples and test the installation. It will
fail if the environment space is inadequate or files are missing or not
installed properly. If it succeeds it will run EXAMPLE\EXAMPLE1.BAT and
create the files SIMPLE.CSV and DTC707A.CSV in the EXAMPLE directory and
pause. Then it will run some reactivity calculations for AIRLMPBS, create
the file REACTEX.CSV in the REACT subdirectory, and show reactivity
results for MIBK. See the comments in those batch files for the programs
they run and the output they produce. Note that your path will be over-
written after you run EXAMPLE.BAT, so you may not be able to use this DOS
window for other programs.
