Plume descriptors derived from a non-Gaussian concentration model

Equations for point-source releases are derived from the non-Gaussian solution to the diffusion equation for (1) the first four moments of the vertical concentration distribution (centroid, variance, skewness, and kurtosis), (2) the magnitude and downwind location of the maximum ground-level concentration, and (3) the plume advection velocity. Equations are obtained for both ground-level and elevated sources. Where applicable, results are compared to wind-tunnel and field measurements and/or to other less generalized equations.
