INPUFF: A Single Source Gaussian Puff Dispersion Algorithm

DESCRIPTION

INPUFF is an air quality model which uses the Gaussian equation to evaluate the diffusion of a puff generated by a single point source. It may be used also with multiple point sources and deals with non reactive pollutants, but may include deposition and sedimentation. The user may choose among different algorithms to simulate the puff behaviour and may also enter its own routines to evaluate the plume effective height and puff dispersion. It works on flat terrains within few tens of kilometers of distance.
