Meiyun's research explores the interactions of air quality with weather and
climate to inform public policy. She is
currently an associate research scholar in Princeton University and a
co-Investigator of the NASA Air Quality Applied Sciences Team. Lin received her PhD from the University of Tokyo in 2007, and carried
out postdoctoral research at the University of Wisconsin, Madison.
During her time at Wisconsin, Meiyun was involved in the UN Task Force on Hemispheric Transport of Air Pollution (TF HTAP)
and coauthored in the 2010 TF HTAP Assessment Report.
A new emphasis in her research since coming to Princeton is to better understand the impacts of imported ozone from hemispheric pollution and natural sources on ozone air quality in western U.S. Understanding the global sources of local pollution is crucial for setting attainable ozone standards for this unique high-altitude region. To determine the extent to which Asian ozone pollution and naturally occurring stratospheric intrusions affect episodes of elevated ground-level ozone in U.S. West, Meiyun analyzed in situ and satellite measurements using a new, global high-resolution version of GFDL chemistry-climate model (AM3). She is also working to examine inter-annual variability and long-term changes of tropospheric ozone in historical records, focusing on their connections with climate variability (e.g. ENSO) and evolving global emissions of ozone precursors. Advancing this knowledge will enable process-oriented assessments of chemistry-climate models, which are needed to build confidence in their utility for projecting tropospheric ozone under future climate scenarios.
Research Interests:
- Global perspective of air pollution in Asia
- Stratospheric impacts on ground-level ozone air quality
- Variability and long-term changes of tropospheric ozone
