Air quality is a major concern in many countries, and the governments are undertaking initiatives to improve it. The primary tool for evaluating these initiatives is air quality modeling.  This course is designed for the senior undergraduate students to learn and practice air quality modeling in the field of environmental science. The course will provide the students with the fundamental knowledge of air pollution dispersion, meso-scale meteorology and three-dimensional Eulerian grid modeling. Theory behind commonly known air quality models, as well as their applications will be covered during the course. Moreover, the students will have opportunities to carry out hands-on exercises to discover potential applications of these models, enhancing their understanding of the course materials.
