A global map of carbon uptake

About Us

Our research is motivated by the compelling need to understand the impacts of climate change and human activities on the Earth’s biosphere and the feedbacks to the climate. We strive to answer major science questions on global carbon/water cycles, climate-vegetation interactions, ecosystem dynamics, and coupled natural and human systems. We combine terrestrial biosphere modeling, remote sensing, field measurements, upscaling, model-data fusion, and statistical analysis to answer these science questions.
