Atmospheric chemistry, including global surface NH3 and NO2 estimates, Nitrogen deposition.

We use the following techniques:
(1) Satellite remote sensing (NO2 and NH3)
(2) Atmospheric chemical transport modeling (GEOS-Chem and MOZART)
(3) Biogeochemical modeling (Biome-BGC and DNDC)
(4) Field measurement including greenhouse gases and N deposition.

We are particularly devoted to modeling the regional nitrogen deposition based on satellite NO2 and NH3 data and atmospheric transport modeling, and assessing nitrogen deposition on the ecosystem using the biogeochemical models. Our research interests include climate change, air pollution, chemical transport modeling and atmospheric remote sensing.
