Abstract A consequence analysis was conducted to investigate the effect on design concentration values resulting from using two different methods for estimating mixing height. Two years of meteorological data from Pittsburgh, PA, Oklahoma City, OK and Brownsville, TX were processed through RAMMET and METPRO meteorological preprocessors. The mixing heights from METPRO were merged with the RAMMET output and separate ISCST2 model runs were made using the two sets of mixing heights from each site and year. The effects of the two mixing-height algorithms on predicted high second-high pollutant concentrations (design concentrations) were compared. The 1-hr design concentrations using mixing height estimates from METPRO were generally larger than those using RAMMET mixing heights for the three point sources by about 20%. Similar results were obtained when the data were paired in time and space. This tendency was not as apparent for other averaging times. For the ground-level area source, the potential for unusually large concentrations from extremely small mixing heights is far greater when using RAMMET mixing heights.
