Abstract

Air pollutant concentrations predicted by the grid-based models are very sensitive to the mixing height. Determining the temporal evolution of the mixing height is a complex problem in air pollution modeling. In this paper, mixing heights derived from three algorithms, RAMMET-X, MIXEMUP, and CALMET are compared with those estimated from the wind profiler data. The results indicate significant differences in the temporal variation of the height of the mixing layer estimated from these methods. The impact of the uncertainties inherent to the estimation of the mixing height profile on the ozone concentrations predicted by the Urban Airshed M
