Abstract

The mixing height is one of the fundamental parameters to characterise its structure and is required in dispersion models. This paper is concerned with the evaluation of the hmix in a coastal area (Esino Valley) by a semi-empirical estimates of boundary layer parameters like the Monin-Obukhov length L and the roughness length ZQ. A preliminary evaluation of the methodology is presented. 1 Introduction Substances emitted into the atmospheric boundary layer are dispersed horizontally and vertically due to the action of turbulence and eventually become well-mixed over this layer. Therefore, it has become customary to use the term "mixed layer" (ML). The mixing height hmLt, in the field of air pollution met
