  • Description:
    A long-range transport and dispersion model which is responsive to the effects of wind shear is documented in this report. The model is especially suitable for calculating concentrations for puff travel times of greater than one day. The effect of wind shear on dispersion is obtained by dividing the pollutant puff within the mixed layer into 300m sublayers at the beginning of each night. Each layer is tracked by means of a separate trajectory. Vertical mixing is resumed during the next day. Further puff divisions occur each night. Example calculations using the model are presented. Descriptions of necessary input parameters are related to the example calculations. The computer code is listed in the Appendix.
