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 کاملRegional US carbon sinks from three-dimensional atmospheric CO2 sampling.
Studies diverge substantially on the actual magnitude of the North American carbon budget. This is due to the lack of appropriate data and also stems from the difficulty to properly model all the details of the flux distribution and transport inside the region of interest. To sidestep these difficulties, we use here a simple budgeting approach to estimate land-atmosphere fluxes across North Ame...
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 کاملPathways for balancing CO2 emissions and sinks
In December 2015 in Paris, leaders committed to achieve global, net decarbonization of human activities before 2100. This achievement would halt and even reverse anthropogenic climate change through the net removal of carbon from the atmosphere. However, the Paris documents contain few specific prescriptions for emissions mitigation, leaving various countries to pursue their own agendas. In thi...
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...
