The lab is dedicated to researching the interactions among atmosphere, biosphere, and human dimension in the context of climate change, chemical element cycles, and policy-making. To study these interactions, a systems approach that integrates the basic principles of biology, physics, and chemistry is used; the knowledge derived from field and laboratory experiments is integrated with the state-of-the-art ecosystems and biogeochemistry models and atmospheric climate and chemistry models; the data of biosphere and atmosphere obtained from field and in-situ measurements and satellite observations are fused with the numerical models.
