Research Abstract |
We seek to improve our understanding of biogeochemical cycles at ecosystem to global scales. This includes using atmospheric trace gas and remote sensing observations in new ways to study the response of ecosystem processes to global change. We use micrometeorological, isotopic, remote sensing, and modeling techniques to study the biosphere at multiple scales. | |
