Oceanic sources, sinks, and transport of atmospheric CO2
[1] We synthesize estimates of the contemporary net air-sea CO2 flux on the basis of an inversion of interior ocean carbon observations using a suite of 10 ocean general circulation models (Mikaloff Fletcher et al., 2006, 2007) and compare them to estimates based on a new climatology of the air-sea difference of the partial pressure of CO2 (pCO2) (Takahashi et al., 2008). These two independent ...
متن کاملInverse estimates of the oceanic sources and sinks of natural CO2 and the implied oceanic carbon transport
[1] We use an inverse method to estimate the global-scale pattern of the air-sea flux of natural CO2, i.e., the component of the CO2 flux due to the natural carbon cycle that already existed in preindustrial times, on the basis of ocean interior observations of dissolved inorganic carbon (DIC) and other tracers, from which we estimate DCgasex, i.e., the component of the observed DIC that is due...
متن کاملSources and sinks for atmospheric N2O
Observations of the temporal and spatial distribution of N,.O in solution are not yet sufficient topermit quantitative assessment of the role of the ocean in the budget of atmospheric N,.O. Consideration of the global nitrogen cycle suggests hat the land should be the primary source of N20. The gas is removed in the atmosphere by photolysis and by reaction with O(•D), and there may be additiona...
متن کاملInferring regional sources and sinks of atmospheric CO2 from GOSAT XCO2 data
We have examined the utility of retrieved column-averaged, dry-air mole fractions of CO2 (XCO2) from the Greenhouse Gases Observing Satellite (GOSAT) for quantifying monthly, regional flux estimates of CO2, using the GEOS-Chem four-dimensional variational (4D-Var) data assimilation system. We focused on assessing the potential impact of biases in the GOSAT CO2 data on the regional flux estimate...
