I'm looking for code to implement a Gaussian plume model in 3D. Any suggestions on where to start? Are there any python scripts out there?
You might check with John Tauxe to see if anyone has ported his ShowFlow2 to python.
There is a freely available Matlab implementation of 3D Gaussian plume. Google for 'gaussianPlume'. Currently, the link is http://www.mathworks.com/matlabcentral/fileexchange/13279-gaussianplume.
