The PBL height or mixing height (MH) is a key parameter in air pollution models determining the volume available for pollutants to dispersion (Seibert et al., 2000) and the struc-ture of turbulence in the boundary layer (Hashmonay et al., 1991). In spite of its importance there is no direct method available to determine the MH. The most common ...

Jan 01, 2000  Jan 01, 2000  The height h of the mixing layer (the mixing height MH) is a key parameter for air pollution models. It determines the volume available for the dispersion of pollutants and is involved in many predictive and diagnostic methods and/or models to assess pollutant concentrations, and it is also an important parameter in atmospheric flow models.
