CARBO-CONTROLE. Quantification of the carbon flux and stocks at the european and national scale

The CARBO-CONTROLE project aims to evaluate the different methodologies to estimate the CO2 flux at the european, national and regional scale. The strategy is to combine a crumbling, down scaling, of the flux at a big scale, by inverting the atmospheric CO2 measures with a aggregation, up scaling, of the national stocks and flux from the climatic parameters of a model of ecosystems.They show that with the monthly data of the global network of CO2 monitoring stations, it is possible to obtain an estimation of the european flux. Meanwhile the errors bond to the leak of continental stations are of the order of the flux average. (A.L.B.)
