A generalized ellipsoidal puff model designed for use in complex terrain has been developed at the Rocky Flats Plant. This paper discusses the model's scheme for determining puff growth and shape. Each puff is defined by six tracer particles. The particles define the edges of the puff (+/- 3sigma) along each of the axes. The particles are advected through a three-dimensional windfield which includes the complex terrain effects of advection, vertical shear, horizontal divergence and convergence, and lofting. The puff axes are not constrained to be orthogonal; thus, the puff assumes an arbitrary shape in response to varying flow and dispersion conditions throughout its volume. 11 references, 2 figures.
