Description: Das Projekt "Der globale Kohlenstoffzyklus und seine Stoerung durch den Menschen und das Klima II - Teil A: Atmosphaere" wird vom Umweltbundesamt gefördert und von Max-Planck-Institut für Meteorologie durchgeführt. An observational program is conducted to record at several key locations the concentration of atmospheric CO2 and its 13C/12C and 14C/C isotope ratios, which provide constraints on the current distribution of surface sources and sinks of CO2. An atmospheric transport model is developed and applied in order to relate the observations from the global station monitoring network to the large scale distribution of surface sources and sinks. Variations of the past atmospheric CO2 concentration and its 13C/12C ratio are determined from analyses on air-bubbles in polar ice cores.These provide a means to assess the natural variability of the carbon cycle during the Holocene and the industrial period. A series of modelling studies of the past 30 years of direct atmospheric observations is conducted, using coupled three-dimensional carbon models of the atmosphere, ocean and terrestrial biosphere driven by observed climate. These studies allow to quantify the regional distribution of sources and sinks of CO2 and provide an assessment of carbon cycle feedbacks induced by climate fluctuations, in particular during El Nino/Southern Oscillation events. Using coupled carbon models of the atmosphere, ocean and terrestrial biosphere, simulations of the atmospheric CO2 concentration evolution are performed given prescribed scenarios of future industrial emissions and land use statistics.
