Description:
In the past decade, recent advances have suggested that convective scaling can be used to parameterize diffusion from a plume in the convective boundary layer (CBL). New methods such as convective scaling need to be explored because the traditionally used Gaussian plume model does an especially poor job in predicting diffusion from an elevated, buoyant plume in the CBL. Briggs (1985) introduced a formula based on convective scaling for estimating surface concentrations from elevated, buoyant plumes the limited-mixed CBL. Briggs strongly recommended that the formula be tested against additional field data. Diffusion data from the Kincaid field experiment (Sponsored by Electric Power Research Institute) was used in the analysis. The results show that the Briggs' formula out performs a Gaussian plume model.
