Any UNIX Environmental Programs?

[jeffcook at cdp.UUCP]

Help!  I am doing graduate work in Environmental Studies at the
University of California, Santa Cruz and am looking for examples
of environmental consultation software.    Right now I am most
interested in locating:
 
-UNIX-based
-public domain
-environmental expert systems
-providing pollution advice
 
I'm also interested in finding out as much as I can about other
environmental consultation programs.  If you can help me,
please drop me a line.
 
I recognize that this field is very new so I am interested in all
works in progress as well.  (Any environmental expert system
authors out there?)  Thanks !!!!
 
 
Yours,
 
Jeff Cook
