Course: Air Pollution Meteorology

Course Description:

This course emphasizes the meteorological processes affecting air pollution problems in the atmosphere and explores the physical and chemical processes in the boundary layer in which the air pollutants from natural and anthropogenic sources are emitted. The fundamental concepts of surface energy budget, continuity equation, atmospheric forces and stability will be discussed. The atmospheric and air pollution modeling will be introduced.
