Research Goal:
To better understand the processes determining the distribution of reactive gases and aerosols, and their implications for air quality, public health, and climate.
Research Interests:
- Atmospheric chemistry and its implications
- Monitoring of trace gases from space
- Modeling of atmospheric composition
Research Techniques:
- Remote Sensing
- Modeling
- Data assimilation
Current Research and Projects:
- Retrievals of HCHO from OMPS and OMI satellites
- Validation of satellite trace gas retrievals
Finished Projects:

- Effect of sea-salt aerosol on tropospheric bromine chemistry (Paper published on ACP)
- Long term trend in HCHO columns over the North America and its driving factors (Paper published on GRL)
- Surface HCHO concentrations retrieved from satellites and the heath impacts (Paper published on ES&T; Media Coverage; Covered by PNAS Front Matter)
- Validation of HCHO retrievals using SEAC4RS aircraft observations (Paper published on ACP)
- Studies of Emissions and Atmospheric Composition, Clouds and Climate Coupling by Regional Surveys (SEAC4RS): GEOS-Chem Team (NASA Group Achievement Award)
