Research
Interest
My main research objective is to understand
physiochemical transformations of atmospheric constituents such as VOCs and aerosols in the troposphere. I particular,
reducing the uncertainties in natural and anthropogenic pollutants
emissions and their impact on regional/global air quality and climate
change are preferred research interest. The specific research topics are as
follows.
- Constrain pollutant
emissions (VOCs, NOx
and aerosols) from space/aircraft observation by applying analytical/ adjoint inverse modeling technique.
- Source appointment of
regional air quality with in-situ measurements by receptor modeling
(factor analysis).
- Analysis of satellite data
for the troposphere (e.g., TES, OMI, MLS, SCIAMACHY, and GOME) to
understand mechanisms of atmospheric transformations and dynamics for tropospheric air quality.
- Regional
and global effects of mega-city pollution with airborne and satellite
measurements.
- Better understand in
natural emissions from the biosphere and its impact on troposphere.
- Potential changes in future
atmosphere due to the use of alternative human energy sources.
