My research interests include using global observations of atmospheric composition in the troposphere to understand global ecosystem gross primary productivity (GPP), Ozone radiative forcing, anthropogenic emission for air quality problems. Human activity has caused emission of both greenhouse gases (GHG), e.g., carbon dioxide (CO2), methane (CH4), and ozone (O3), and air pollutants, e.g., nitrogen oxides (NOx), carbon monoxide (CO), ammonia (NH3), volatile organic compounds (VOC), and particulates (PM2.5). The increase of these emissions causes degradation of air quality that not only affects human health but also damages our ecosystem and then impacts the future climate through the carbon and water cycles. The recent development of our observation instruments and technology (ground-based, airborne, and space-borne) allows us to monitor global trace gases at multi-spatial and temporal scales. These growing data are helping us to improve our knowledge of the distribution and trend of the trace gases and their emissions and further the impacts on air quality and future climate.
