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 main aim of the new department is to study and interpret observed large-scale biogeochemical signals in the Earth system by linking these signals to process-understanding and process-oriented modelling of key processes in the terrestrial biosphere. To accomplish this goal, the group develops and employs numerical models of terrestrial biosphere processes, and develops new observational constraints obtained from biosphere monitoring or ecosystem manipulation to challenge model formulations. An improved representation of key (eco-physiological) processes, in particular those affecting nutrient availability and its role in ecosystem dynamics, is a key component of the group's research. The group investigates the consequences of the coupling of the terrestrial biogeochemical cycles for biogeochemical and biogeophysical interactions with the climate system.
