The goal of the course will be to provide the students with an understanding of the fundamental principles of air quality modelling, the use of screening and advanced air dispersion models, as well as the limitations of these tools in actual practice. The course will also address other relevant air quality related subjects such as ambient monitoring and dispersion model verification. The course will be structured to provide sufficient background in dispersion modelling theory to allow the users to make informed decisions on model inputs, modelling methodologies and approximations. The course will feature both theory sessions as well as hands-on training in the use of dispersion models (US EPA SCREEN 3 and AERMOD models) and data processing.
