Overview

The Biogeochemical Signals department is a newly formed department succeeding the former Biogeochemical Systems department headed by Prof. Dr. Martin Heimann, and the former research group on Terrestrial Biosphere Modelling. The department investigates large-scale signals of biospheric processes and their feedbacks to the climate system. We integrate bottom-up process-driven modeling with top-down constraints inferred from remote-sensing, atmospheric observations and atmospheric inversions. We aim to utilize novel data sources to develop a better predictive understanding of important land-based processes at local to global scales. Our goal is to contribute to a better understanding of recent biogeochemical patterns and trends, as well as to improve predictions of land-climate feedbacks and of the consequences of climate mitigation efforts in future decades.
