Volatile organic compounds (VOCs): global and regional emissions and impacts

Team members: Hansen CAO, Heng TIAN

Volatile organic compounds (VOC) impact the oxidizing power of the atmosphere and produce ozone and secondary organic aerosols. VOCs are emitted into the atmosphere from both natural and anthropogenic activities, and quantifying these many overlapping sources can be a challenge. We use remote sensing (satellite) and in situ observations to make 'top-down' estimates of VOC emissions from different sources.

Secondary organic aerosols (SOA)

Team members: Nan LI, Li XING, Tzung-May FU

Secondary organic aerosols (SOA) are the organic mass transferred into the particulate phase in the atmosphere. Many recent observations have found SOA concentrations to be much higher than can be explained by current models in most parts of the atmosphere.

Using a global 3-D atmospheric chemistry model, we investigate the missing source of SOA. In particular, we find that the heteorogeneous uptake of dicarbonyls in aeorsols and clouds can help explained the observed SOA concentrations and variability.

Air-sea exchange of organic materials

Team members: Cenlin HE, Tzung-May FU

The ocean can act both as a source and a sink of atmospheric organic material. The air/sea exchange of organic materials is complexly regulated by both physical and biological conditions at the interface and poorly understood. We developed a new conceptual model to account for these physical and biological processes, including the presence of microfilms, production/consumption of organic matter by marine life, and other photochemical processes.
