This course will cover fundamental science and engineering principles dealing with air environmental systems. First, we focus on what pollutants can be present in air and how these pollutants move and spread in the air. Second, we will investigate indoor air quality and macroscale air-related problems including acid rain, ozone depletion, and global warming. Finally, we will study the impact of climate change on our lives and our environment and how we can mitigate greenhouse gas emissions and adapt to the change.
