We are a multidisciplinary group of researchers concerned with understanding the fundamental factors (both natural and anthropogenic), which determine the chemical composition of the Earth's atmosphere.

Our major research interests include quantifying and modeling emissions of atmospheric trace gases (carbon dioxide, methane, nitrous oxide) with temperate, boreal, and tundra forest ecosystems, from global energy production and use, large–scale agroecosystems, and tropical areas subject to land use change.

We represent researchers from many institutions working collaboratively and internationally through research and education with one common goal—to increase our understanding of the natural and anthropogenically induced changes in the exchange of radiatively important trace gases.
