Advisory Prerequisites: General Chemistry, Introductory Physics
Description: Aerosols have global implications for human health and climate, but are challenging to understand due to their complex physical and chemical properties that determine their behavior in the atmosphere. This course will explore be divided into three major sections: aerosol physics, aerosol chemistry, and aerosol impacts.
Course Goals: - Learn about how to describe particles and particle populations through different physical properties: particle diameters, concentrations, morphology, and size distributions
- Describe particle motion under different flow regimes, such as turbulent or laminar, through the use of Reynolds numbers, Stokes' Law, electrical fields, and Brownian motion.
- Explore processes that modify particle physical properties, including: condensation, evaporation, and coagulation.
- Describe the chemical composition of aerosols and the sources, heterogeneous reactions, and other processes that modify aerosol composition.
- Discuss the strengths and weaknesses of different characterization methods for aerosols, including: gravimetric analysis, electron microscopy, light scattering, mass spectrometry, and spectroscopy.
- Explore the impacts of atmospheric particles on health through inhalation and climate through light scattering or cloud formation.
Competencies: - Develop the ability to interconvert between different types of particle diameter and utilize particle size distributions to describe particle populations.
- Be able to mathematically solve for aerosol motion and losses in different types of flow.
- Understand how to solve for particle modification in different chemical environments.
- Gain the ability to make informed decisions about which characterization technique is appropriate for different applications.
- Be able to explain the impacts of aerosols on health and climate and the benefits and challenges of different actions, such as regulation, to mitigate aerosol effects.
