Abstract
High frequency wind fluctuation data were used to estimate the dispersion near roadways. The standard deviations of the wind direction and the elevation angle were computed for six averaging times. The EPA HIWAY model was modified to use these fluctuation statistics directly to estimate dispersion. The data from the General Motors Sulfate Dispersion Experiment were used in this study. In particular, the data used in this pilot study were three half-hour periods when the winds were nearly parallel with the test track. Results from analysis show that model performance was improved for parallel wind conditions when the fluctuation statistics of the wind were used to estimate dispersion. The results also show that model estimates are most sensitive to the vertical dispersion parameter. Concentrations seem to be insensitive to the horizontal dispersion parameter.
