Project Description
Why Attend
It has been known for millennia that people with certain occupations, such as miners, incurred diseases of the lungs and respiratory system. Today we know that many of these effects were not only induced by fine particles and toxic metals but also by carbon monoxide. Radon gas also was one of the contributing factors to miners’ lung disease from the 15th through the 20th centuries in the Erzgebirg Mountains in central and eastern Germany.
Emissions from cooking, heating, and fires in general were also well known. Apart from nature, the sources of contamination were simple solid fuels and metal working operations. Odours also were a part of common life. The common approach to air quality management was to stay out of “bad air” (mal aria), or out of areas in which refuse, garbage, and human corpses were deposited in ancient times.
Only in the last decades of the 20th and the first decade of the 21st century have air quality management strategies taken hold. In the last 30 years, there have been significant reversals in earlier air quality trends from increasingly poor air quality to increasingly healthy air quality. This change has come about as a result of dedicated people and of societal decisions to pursue clean air as a priority. Most significant, this change has come at a time when the worldwide population has been increasing.
Air quality models use mathematical and numerical techniques to simulate the physical and chemical processes that affect air pollutants as they disperse and react in the atmosphere. Based on inputs of meteorological data and source information like emission rates and stack height, these models are designed to characterize primary pollutants that are emitted directly into the atmosphere and, in some cases, secondary pollutants that are formed as a result of complex chemical reactions within the atmosphere. These models are important to our air quality management system because they are widely used by agencies tasked with controlling air pollution to both identify source contributions to air quality problems and assist in the design of effective strategies to reduce harmful air pollutants. For example, air quality models can be used during the permitting process to verify that a new source will not exceed ambient air quality standards or, if necessary, determine appropriate additional control requirements. In addition, air quality models can also be used to predict future pollutant concentrations from multiple sources after the implementation of a new regulatory program, in order to estimate the effectiveness of the program in reducing harmful exposures to humans and the environment.
The course takes an in-depth look at the fundamentals of air pollution modelling: from a review of air pollution meteorology, to an introduction to Gaussian plume models; from a discussion of plume rise formulations, to a review of Eulerian grid models. With individual sections, this course gives environmental professionals a solid foundation for understanding modelling techniques using both semi-empirical formulations and well-established atmospheric science.
