Research
Interest
- Interpreting
MLS Tropical Upper Tropospheric Ozone Observations with GEOS-Chem.
- Developed,
implemented and monitored an operational 3-D Air Quality Forecast
Modeling System (AQFMS), which is run daily to provide experimental
forecasts of both gas phase and particulate matter air pollutants
for the Northeast United States.
-
Studied the HOx chemistry for an urban site in New York City using
both model and observation data to investigate the chemical mechanisms
that contribute to the oxidizing capacity of the atmosphere during
summer and winter and the uncertainties therein.
- Cirrus
clouds and global climate.
- Integrated
the surface heterogeneous reactions for HONO formation in the
3-D AQFMS and analyzed their impacts on the HONO concentrations
and the concentrations of HOx and O3 as well.
