Abstract - Two recent dispersion experiments conducted to distances of 100 km were used to verify a mesoscale trajectory-diffusion model. Both experiments were conducted during the daytime under very unstable conditions. Vertical mixing coefficients of 30-60 m2/s were required for calculations to match observed concentrations. The type, spacing, and frequency of observed winds used to compute the model's advection term were found to significantly affect the calculated trajectories when wind flows were complex.
