Brief Bio

Dr. Qing Liang is a research physical scientist in the Atmospheric Chemistry and Dynamics Laboratory. Dr. Liang received her Ph.D. in Atmospheric Sciences in 2006 from University of Washington, Seattle, and has been at the NASA Goddard Space Flight center since graduation. Her research has focused on using Global 3-Dimensional Chemistry Models to simulate atmospheric transport and chemistry of compounds that are crucial to tropospheric and stratospheric ozone, e.g., the anthropogenic ozone precursors that are relevant for tropospheric ozone, the man-made ozone depleting substances and the very-short-lived halogen compounds, both natural and man-made, that are important for stratospheric ozone. One primary objective of Dr. Liang’s research is to use NASA data from various observation platforms, surface, airborne, and satellite, to improve our understanding and simulation of these key atmospheric compounds.
