Screen View™ - Freeware
Sceening Air Dispersion Model

http://www.weblakes.com/products/screen/index.html

Screen View is a user friendly interface for the U.S. EPA screening model, SCREEN3. 

The SCREEN3 model can be used to estimate worst-case ground level concentrations for a single source as well as concentrations in the cavity zone, and concentrations due to inversion break-up and shoreline fumigation. 

Screen View can model scenarios with simple or complex terrain, with or without building downwash and give results at discrete or automated distances. SCREEN3 is the screening version of the ISC3 model. Preliminary modeling with Screen View can remove the need for more complicated modeling, saving you time and resources.
