Abstract

With respect to the predicted climate changes and the rise in the concentration of atmospheric CO2 it has become evident that the role of terrestrialecosystems in the global carbon (C) turnover is not yet fully understood. This is also true for C fluxes in agricultural ecosystems. As rising atmospheric CO2 concentrations will directly affect plant photosynthesis, plant biomass production and plant water relations and fluxes of other elements, it is of particular importance to predict the dynamics of C fluxes between the atmosphere and agricultural canopies and the potential consequences for agroecosystems under future atmospheric CO2 conditions. Currently there arehardly any experimental approaches under real field conditions in crop rotation systems to measure C fluxes at larger spatial scales and to simulate future CO2 scenarios. The Braunschweig Carbon Project is a combination of micrometerological flux measurements of atmospheric trace gases and other air constituents and of a large scale free air carbon dioxide enrichment (FACE) experiment. The project which is unique in the the combination of these two approaches is especially designed to meet the requirements of process and landscape models and to contribute to the improvement and validation of models to predict the consequences of climate changes for agricultural ecosystems. The present paper is a description of the structure and design of the experiment.
