I'm interested in doing a survey of chemical plume/dispersion modelin g softwares, which I could then present at a future friday lunch presentati on at my company.  

Specifically, I'm interest ed in acute atmospheric release, accounting for topological and urban barri ers, of industrial chemicals. 

Though, if all we can find are 2 dimensional open plane software examples, it may still be interesting to compare. 

If anyone has any re commendations, please send them to me on or off list. I'd appreciate any as sistance, pointers, or general user feedback regarding these software appli cations. 

Thanks,

Craig
