Objetivo SIMULATION OF CARBON CYCLE AND CO2-CONCENTRATION IN THE ATMOSPHERE. A SERIES OF PROCESS AND SENSITIVITY STUDIES WILL BE CARRIED OUT 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. IN THE RECENT PAST, SEVERAL HIGH RESOLUTION MODELS OF INDIVIDUAL CARBON POOLS HAVE BEEN DEVELOPED BUT A SYSTEMATIC COUPLING OF THEM HAS NOT YET BEEN UNDERTAKEN. IT IS PROPOSED TO IMPROVE AND FINALLY COUPLE THE FOLLOWING, ALREADY EXISTING CARBON MODELS : - 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.
