We are investigating biosphere-atmosphere interactions on scales of individual cells to the whole earth system to improve predictions of biogeochemical fluxes, atmospheric composition, air pollution, climate and ecosystem health. This is being accomplished through multidisciplinary field, laboratory and modeling studies of the processes controlling these interactions.
Our current research activities include
USA: Alaska, California, Texas
International: Thailand, Brazil, China, Colombia, Korea, Antarctica
Heat, ozone and drought stress
Emission Factor variability
Total OH reactivity and aerosol production
Gene upregulation of BVOC emission
MEGAN biogenic emission model development
BVOC emission response to stress
Our core capabilities include:
Field deployable systems: PTR-TOFMS, portable GC-MS, Photosynthesis/respiration, enclosure systems, sonic anemometers, sampling systems for solid absorbent tubes, stainless steel canisters and glass bottles
Laboratory facilities: TD-GC-TOFMS (for tubes and canisters), environmental growth chambers, online instruments for CO2, H2O, VOC analysis, Chlorophyll
Modeling : MEGAN BVOC emission modeling, CESM global earth system modeling, WRF-Chem regional air quality modeling
We work closely with the Biosphere-Atmosphere-Human Interaction Research Group led by Dr. Saewung Kim.
