This course is concerned with physical and chemical properties of aerosols and their impacts on earth's climate, air quality, and human health. This course will cover the fundamentals of aerosol physics and chemistry, and relate these principles to the overall impacts. The first section will cover single particle processes (particle drag, gravitational settling, diffusion) and evolution of an aerosol population (new particle formation, condensation and coagulation, deposition and cloud droplet formation). In the second section, the various components in atmospheric aerosol will be discussed in detail, including kinetics and thermodynamics of organic and inorganic compounds. Applications to industrial processes, such as drug delivery and chemical manufacturing, will also be explored. This course is critical to those students pursuing careers in atmospheric science and air pollution control, who will need to measure, model, and control airborne particles.
