Abstract: To assess the ability of a model to simulate atmospheric dispersion, its performance must be tested using data from real field experiments. This paper presents the results of a validation study of the atmospheric dispersion model Dispersion over Complex Terrain (DIPCOT) against data from the Indianapolis field experiment. Three different modules of the dispersion code are examined a puff model, a random walk model based on random displacement, and a stochastic model based on the Langevin equation. The results of the three modules are statistically and qualitative compared with the maximum arcwise concentrations and the near centreline concentrations.
