Seminar: Global-through-Local Environmental Modeling

Wed, April 26 at 10:00 am
JHU Homewood campus - Ames Hall, Room 302
3400 N. Charles St, Baltimore, MD 21218

Join the JHU Department of Environmental Health and Engineering for a seminar with Dr. Yang Zhang from North Carolina State University for a look at modeling projects that integrate research in air pollution, climate change, water-carbon cycle, and human health. 

About the Topic

Air pollution and climate change are two major environmental challenges that we are facing. Both have significant impacts on human, environment, and the entire Earth system that encompasses air, water, land, ocean,and ecosystem. 

Air pollution has become the world’s largest single environmental health risk, responsible for 7 million people deaths per year worldwide. Adverse climate change such as heat wave, drought, wildfires, or compounding climate extremes will further increase annual air pollution-related deaths. Reducing air pollution and mitigating adverse climate change will therefore save millions of lives in theworld.Global- through-local environmental models provide powerful tools to simulate the sources, fates, and environmental impacts of air pollutants such as tropospheric ozone and fine particular matter and to assess the co-benefits of integrated strategies for air quality control, climate change mitigation, ecosystem management,and human health protection.

This seminar will present the latest research at the interdisciplinary nexus of air pollution, climate change, water-carbon cycle, and human health.  It will start with a brief review of history and current status of air quality,climate, and Earth system modeling. This will be followed by a detailed presentation of model development, improvement, evaluation, and decadal-scale application of the state of the science technology-driven Earth system model to demonstrate the current models’ capability in reproducing atmospheric observations, studying the impacts of climate change on air quality, water resources, and forest ecosystem at various spatial scales, and supporting win-win emission control strategies in mitigating adverse climate change, air pollution, and water shortage.

Several new projects that integrate air pollution and climate research with energy/emission projection, human exposure/health assessment,and cost-benefit studies will also be highlighted. Finally,future research challenges and directions will be discussed in the context of global changes, energy transition, environmental sustainability, and policy implications.

Meet the Presenter

Dr. Yang Zhang is professor of air quality and climate at North Carolina State University. She specializes in numerical modeling and theoretical study of atmospheric chemistry/air quality engineering. Her research interests include air pollution modeling and assessment, atmospheric chemistry and transport, chemistry and dynamics of atmospheric aerosols, sensitivity, uncertainty, and process analysis, and interactions among air quality, meteorology, and climate change.  

Dr. Zhang received her PhD in Chemical and Biochemical Engineering from the University of Iowa and BS in Environmental Engineering from Tsinghua University. Learn more about her work

All things appear and disappear because of the concurrence of causes and conditions. Nothing ever exists entirely alone; everything is in relation to everything else.
