Sources 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 کاملBacterial sources and sinks of isoprene, a reactive atmospheric hydrocarbon.
Physiological and biochemical processes in bacteria can have important impacts on the atmosphere. For example, methane is produced by anaerobic methanogens and then released from soils, sediments and ruminant animals to contribute to the atmospheric `greenhouse' effect (Crutzen, 1991; Conrad, 1996). Interestingly, it is estimated that the fraction of methane that reaches the atmosphere is only ...
متن کاملOceanic 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 کاملSources of the oxygen isotopic anomaly in atmospheric N2O
[1] One-dimensional and two-dimensional models are used to investigate the isotopic composition of atmospheric N2O. The sources of N2O in the atmosphere are based on recent laboratory measurements of the N2O quantum yield in the mixture of O3/O2/N2 (Estupiñán et al., 2002). Two recently proposed pathways (Estupiñán et al., 2002; Prasad, 2005) are evaluated in the model. We find that the new atm...
