Description
Different atmospheric stability schemes were used to characterize the plume growth (dispersion coefficients σ) in the lateral and vertical directions to determine the concentration distribution of pollutants through the PBL. The PBL is the region in which surface friction has a large effect on the mixing of pollutants. It is also suffer large fluctuation in temperature and wind and its depth (mixing depth) changes over a diurnal cycle. In this study, four months of surface meteorological parameters were used (to represent different seasons) to determine seasonal stability, classification. Five different stability schemes were estimated based on temperature gradient, standard deviation of the horizontal wind direction fluctuation, gradient and Bulk Richardson numbers and Monin-Obukhov length. Friction velocity, (u*) for each stability scheme was estimated for characterizing the hourly, mixing height for each stability class. Also, plume rise was estimated for each stability class depending on the availability of meteorological parameters
