Cel SIMULATION OF CARBON CYCLE. THE GOAL OF THE STUDY IS THE SIMULATION OF THE CARBON CYCLE AND THE CONCENTRATION OF ATMOSPHERIC CARBON DOIXIDE (CO2) ON TIME SCALES RANGING FROM A FEW DAYS TO SEVERAL HUNDRED YEARS (COVERING THE INDUSTRIAL EPOCH) BY MEANS OF COUPLED MULTIDIMENSIONAL CARBON MODELS OF THE ATMOSPHERE, THE OCEAN AND THE TERRESTRIAL BIOSPHERE, AND THEIR VALIDATION THROUGH EXPERIMENTAL DATA. TO ACHIEVE THIS GOAL A SERIES OF PROCESS AND SENSITIVITY STUDIES ARE PROPOSED IN CONJUNCTION WITH MODEL SIMULATION EXPERIMENTS. A SUCCESSFUL SIMULATION OF THE OBSERVED CARBON CYCLE FEATURES WILL ALLOW THE ESTABLISHMENT OF A REGIONAL INVENTORY IN SPACE AND TIME OF SOURCES AND SINKS OF CARBON AT THE SURFACE OF THE EARTH. FURTHERMORE, BY VIRTUE OF USING PROGNOSTIC MODELS OF THE OCEANIC AND TERRESTRIAL BIOSPHERE CARBON POOLS, IT WILL BE POSSIBLE TO ESTIMATE POTENTIAL CAPACITIES OF INDIVIDUAL SOURCE/SINK REGIONS WITH RESPECT TO FUTURE ANTHROPOGENIC CO2 EMISSION SCENARIOS, BUT ALSO TO POSSIBLE CHANGES IN CLIMATE. THE FOLLOWING, EXISTING CARBON MODELS WILL BE IMPROVED AND COUPLED : - A MODEL OF THE TERRESTRIAL BIOSPHERE DEVELOPED AT THE UNIVERSITY OF OSNABRUCK, - A THREE-DIMENSIONAL OCEANIC MODEL BASED ON THE CURRENT FIELDS OF A DYNAMICAL GLOBAL MODEL OF THE OCEANIC GENERAL CIRCULATION, DEVELOPED AT THE MAX-PLANCK-INSTITUT FUR METEOROLOGIE IN HAMBURG, - A GLOBAL THREE-DIMENSIONAL ATMOSPHERIC TRANSPORT MODEL, BASED ON OBSERVED WINDS OF THE PERIOD 1978-79. IN PARTICULAR THE FOLLOWING PROCESSES, INFLUENCING THE CARBON SYSTEM ON THESE TIME SCALES, WILL BE INVESTIGATED : - MECHANISMS OF GAS EXCHANGE BETWEEN THE ATMOSPHERE AND THE OCEAN; - EXCHANGE FLUXES OF CARBON BETWEEN THE ATMOSPHERE AND THE BIOSPHERE (INCLUDING RESPONSES OF THE TERRESTRIAL BIOSPHERE TO CLIMATIC FLUCTUATIONS AND HUMAN INFLUENCES); - FEEDBACK MECHANISMS THROUGH ENHANCED ATMOSPHERIC CO2 LEVELS UPON THE TERRESTRIAL BIOSPHERE; - FEEDBACK MECHANISMS THROUGH CLIMATE UPON OCEANIC AND BIOSPHERIC CARBON POOLS.
