A method for calculating the dispersion of plumes in the atmospheric boundary layer is presented. The method is easy to use on a routine basis. The inputs to the method are fundamental metereological parameters, which act as distinct scaling parameters for the turbulence. The atmospheric boundary layer is divided into a number of regimes. For each scaling regime the authors suggest models for the dispersion in the vertical direction. The models directly give the crosswind-integrated concentrations at the ground for nonbuoyant releases from a continuous point source. The method is limited to horizontally homogenous condition and travel distances less than 10 km.
