Abstract The conference preprint describes the results of the first performance evaluation of the Complex Terrain Dispersion Model (CTDMPLUS), which is currently being considered by the USEPA as a regulatory guideline model. The CTDMPLUS performance is also compared with that of Rough Terrain Diffusion Model (RTDM). For the one-year Lovett Power Plant data base, where plume impaction is fairly uncommon, CTDMPLUS tends to overpredict the high end of the concentration distribution by about a factor of two for 1-hour, 3-hour, and 24-hour averages. In comparison, RTDM overpredicted the high concentrations by about a factor of five.
