My name is Fang-Yi Cheng. I received a bachelor’s degree in Atmospheric Sciences from National Central University (NCU), Taiwan, and a Ph.D. in Earth and Atmospheric Sciences from the University of Houston. In August 2009, I joined the Department of Atmospheric Sciences at National Central University, where I am currently a full professor. 

My research integrates boundary-layer and urban meteorology with chemical transport modeling to examine PM2.5 and ozone formation, source–receptor relationships, and the impacts of meteorological and climate variability on air quality. Through the use of WRF–CMAQ simulations, observational analyses, and process-based diagnostics, my work aims to advance understanding of meteorological controls on pollutant transport, transformation, and accumulation, and to support the development of effective air pollution mitigation and control strategies, particularly in urban and coastal regions.

Our laboratory focuses on air quality research from an integrated, multidisciplinary perspective, encompassing meteorology, emissions, and atmospheric chemistry. We aim to advance the understanding of the physical and chemical processes governing air pollutant formation, transport, and dispersion, with particular emphasis on boundary-layer dynamics, urban meteorology, and extreme air pollution events.

Our research approach relies on the integration of numerical air quality modeling, ground-based observations, and satellite remote sensing data. By combining chemical transport models (e.g., WRF–CMAQ) with observational analyses, we evaluate model performance, diagnose key processes, and improve forecasting capability. Through close collaboration with government agencies and industry partners, our work supports air quality forecasting, early warning systems, and science-based pollution mitigation strategies.
