Notes on the Process Analysis example
(Revision date:  2/8/00)

For those who are interested in using the Process Analysis 
capabilities of UAM-V version 1.30, this directory includes sample
files for exercising that option.  To utilize the samples provided
here, you should already have installed UAM-V 1.30.

The files and code used in analyzing the data are included in the
compressed tar files called pasampl.tar.  Retrieve the files in the
tar file using the command 

tar -vxf pasampl.tar

For the simplest installation, you should be in the directory
above the already installed "sample" and "src" directories when you 
issue the tar command.  When located at the proper directory, the
"ls" command should show

read_me    sample     src

and after running the tar command, "ls" should show

pa.sample  read_me    sample     src  

In the src directory, two new directories will be added.  The vpost8
directory contains a program to extract information from the binary
process analysis data files that are saved during a UAM-V simulation.
For those who have the SAIPLOT graphics system installed, the program
pairrps1.1 is provided to prepare graphs of the PA data.  If you do
not have the SAIPLOT system, then the output from vpost8 can be
imported into a spreadsheet or graphics program for display.  Both
the vpost8 and pairrps1.1 code must be compiled on your system
before they can be used.  Makefiles are provided for DEC Alpha 
systems, but these may need to be adapted for your particular system.

The directory pa.sample will also be created.  Under pa.sample/run, 
sample jobs and input files for running UAM-V with the PA option
enabled are included.  The job files included here utilize a number
of files from the original installation of the UAM-V 1.30, so 
following the recommended directory structure will make testing
the sample jobs a simple matter.  Under pa.sample/output are the
output files from the sample run.  Under pa.sample/vpost are sample
jobs to extract information from the PA files. And finally, under
pa.sample/pltpa are jobs to prepare graphics using the SAIPLOT
graphics system.

For those who are not using SAIPLOT, an example is included of 
importing some of the PA data into an Excel spreadsheet.  In the
directory pa.sample/output/asc, the command script o3grep.cs can
be run which will create a text file called o3c18.txt.  This file
can be imported into Excel as a fixed width file.  Copy the block of
numeric data onto the clipboard.  The data can then be pasted at 
cell B2 onto the "o3c18.txt" sheet in the sample spreadsheet 
pa18o3.xls.  Several example graphs are included.

Finally, an example of how process analysis can be used to examine
and interpret UAM-V simulation results is provided in the Powerpoint
presentation procanal.ppt entitled "Process-Based Analysis of the 
Role of the Gulf Breeze in Simulating Ozone Concentrations along
the Eastern Gulf Coast."  This presentation is included in the 
pa.sample directory and is posted separately under the information
section on the UAM-V web site.
