The biosphere has a significant impact on the composition of the atmosphere. One of the greatest uncertainties of future climate predictions is the impact of anthropogenic activities on the dynamic exchange processes between the atmosphere and the biosphere.
Main objectives of the Biosphere Research Area of IMK-IFU are
- to study the impacts of changes in climate, atmospheric deposition of nutrients/pollutants and land use (Global Changes) on the terrestrial biosphere,
- to quantify global change effects on ecosystem C/N stocks and exchange processes between the terrestrial biosphere, the atmosphere and hydrosphere with a specific focus on C and N trace gases, and
- to understand better the complex feedback mechanisms between the biosphere and atmosphere under changing environmental conditions.
Our aim is to improve our understanding of the biosphere as a system by application of an integrated research approach of process studies, field studies, and process modelling. The data sets gained in the laboratory, at longterm field stations and selected satellite sites are used to develop further, to improve and validate process-based models.
