Lung-Wen "Antony" Chen

Associate Research Professor
Division of Atmospheric Sciences

Dr. Chen's research interests include studying sources, evolution, and environmental impacts of atmospheric trace gases and aerosols, through field/laboratory experiments and receptor modeling. Dr. Chen conducted the Maryland Aerosol Regional Characterization (MARCH-Atlantic) study, wherein he developed a source apportionment technique coupling factor and ensemble air parcel back trajectory analyses. He is currently involved in the PM2.5 and VOCs source apportionment projects in Hong Kong, China, California, and the U.S. east coast. Particular focus of his research is on improving techniques for the quantification of light-absorbing carbonaceous aerosol. Dr. Chen has been investigating various thermal evolution methods as well as in-situ or time-integrated optical measurements. This research provides insights into the current emission inventories and radiative forcing estimates.

RESEARCH AREAS:

• Characteristics of trace gas and particle emissions from combustion sources with a focus on carbonaceous material; evolution of pollutants in the atmosphere and associated environmental/radiative impacts; novel techniques for quantifying light-absorbing carbonaceous aerosol.
