Ambient air quality has improved significantly since the middle of the 20th century, but air quality management remains a priority to reduce the impact of air pollution on public health and to meet targets set by legislation. Atmospheric dispersion models can be cost-effective tools which complement monitoring in air quality management programmes. They are also invaluable in emergency planning for dealing with instantaneous releases from industrial and other sources of contaminants.
This concise introductory handbook outlines the key characteristics and general principles of modelling, and how these translate into practical modelling tools. It introduces several types of model used for air quality management, presents the skills necessary for using simple dispersion models, guides the reader through the interpretation of results drawn from computer models of real problems, identifies limitations of dispersion models and offers guidelines for good practice.
With extensive examples and illustrations of the software, and including exercises and solutions, this is an essential tool for planners, engineers, policy makers and businesses. It will also be useful to students on environmental science courses in which modelling is a component.
