Course Name: Diffusion and Transport of Air Pollutants (ES 640)
Year Offered: Graduate
Keywords: Air Quality and Pollution Control
Content: Micrometeorology fundamentals, variation of wind, temperature and water in the lower layers of the atmosphere energy and moisture balances. Flux profile relationships. Estimation of atmospheric dispersion - diffusion equations, effects of stability, estimation of vertical and horizontal dispersion, evaluation of wind speed, accuracy of estimates, calculation of maximum ground level concentrations, estimates of deposition. Effective height of emission and maximum concentration, estimate of required Stake heights, effects of evaporative cooling, effect of aerodynamic downwash, effects of gravity. Concentrations in an inversion, break-up fumigation, plum trapping, concentrations at ground level compare to concentrations at the level of effective stake height from elevated continuous sources, total dosage from a finite release, cross wind integrated concentration, estimation of concentration for sampling times longer than a few minutes estimation of seasonal or annual average concentrations at a receptor from a single pollutants source. Meteorological conditions associated with maximum ground level concentrations - Concentrations at a receptor point from several sources - instantaneous sources - relation to other diffusion equations. Urban air pollution models: different types, their accuracies and transport models. Air quality standards, emission standards, industrial meteorology and maximizing the dilution capacity of the atmosphere. Effects of air Pollution on man and materials-Environmental Impact Assessment studies related to air Pollution and in siting industries.
