Estimation of Atmospheric Boundary Layer Parameters for Diffusion Applications

TLDR

The paper extends an introductory presentation from the 1984 Workshop on Updating Applied Diffusion Models in Clearwater, Florida. The study outlines a meteorological preprocessor for air‑pollution modeling. The approach applies meteorological preprocessing techniques to level terrain, accommodating non‑homogeneous conditions. The methods extract substantially more information from routine data than Pasquill classes, can incorporate special measurements, and improve planetary boundary‑layer characterization for more accurate diffusion modeling.

Abstract

This paper gives the outline of a "meteorological preprocessor" for air pollution modeling. It is shown how significantly more information can be extracted from routinely available measurements than the traditional Pasquil stability classes and power law wind speed profiles. Also it is shown how additional special measurements—if available—can be accommodated. The methods are primarily intended for application in generally level, but not necessarily homogeneous terrain. The improved characterization of the state of the planetary boundary layer allows a more modern and probably more accurate description of diffusion. The paper is an extended version of an introductory paper presented during the "Workshop on Updating Applied Diffusion Models" Clearwater, Florida, January 1984.
