Boundary Layer Parameterization for a Non-Gaussian Puff Model

Abstract

The paper presents two boundary layer parameterizations for a model based on a general technique for solving the K equation using the truncated Gram–Charlier expansion (type A) of the concentration field and a finite set of equations for the corresponding moments. The two parameterizations allow the model to be applied routinely using as input simple ground-level meteorological data acquired by an automatic network. A preliminary performance evaluation is shown in the case of continuous emission from an elevated source in a variable boundary layer (with a time resolution of 10 min).
