Topic:

A Few Words about Atmospheric Aerosols

Aerosol particles are particles suspended in the atmosphere. They enter the atmosphere from various natural and anthropogenic sources or through secondary formation in the air. Atmospheric aerosol particles are closely related to our daily lives. From the quality of air we breathed in every minute to the clouds and rain we experienced to Earth’s climate change, atmospheric aerosol particles play a role. Once entered the atmosphere, aerosol particles can be carried along the wind and transformed chemically and physically. Therefore, their impacts on air quality and climate change are locally, regionally and globally. To achieve a cleaner environment and climate mitigation, it is important to understand how atmospheric aerosol particles impact air quality and climate change. In this seminar, I will briefly introduce how atmospheric aerosol particles affect air quality and climate, and share some of my past studies in these aspects.


Speaker:

Dr. Joseph Ching

Assistant Professor, Arid Land Research Center of Tottori University, Japan

Joseph Ching is an assistant professor (specially appointed) at Arid Land Research Center of Tottori University, Japan. His current research interest lies in atmospheric aerosol, air quality and climate. After receiving his bachelor and master degrees in Physics from the University of Hong Kong, he went to Illinois, US to pursue PhD study in atmospheric sciences in the University of Illinois at Urbana-Champaign (UIUC), where he developed an interest in atmospheric aerosol particles and their impacts on clouds and climate, with a specific focus on black carbon particles. After his PhD study, he joined Pacific Northwest National Laboratory (PNNL) in the US as a postdoc working on atmospheric aerosol modeling. In 2017, he moved to Japan Meteorological Research Institute under Japan Meteorological Agency (JMA), where he extended his research to the relationship between aerosol particles, air quality and public health.
