Sentences with phrase «global atmospheric lifetime»

Such feedbacks cause the decay time of a perturbation (τpert) to differ from the global atmospheric lifetime (τglobal).

The global atmospheric lifetime characterises the time to achieve an e-fold decrease of the global atmospheric burden.

Another feedback has been identified for the addition of N2O to the atmosphere; it is associated with stratospheric O3 chemistry and shortens the perturbation lifetime relative to the global atmospheric lifetime of N2O by about 5 %.

The following lifetimes may be distinguished: ► Turnover time (T)(also called global atmospheric lifetime) is the ratio of the mass M of a reservoir (e.g., a gaseous compound in the atmosphere) and the total rate of removal S from the reservoir: T = M / S. For each removal process, separate turnover times can be defined.

Not exact matches

«It is ironic that high concentrations of molecules with high global warming potential (GWP), the worst - case scenario for Earth's climate, is the optimal scenario for detecting an alien civilization, as GWP increases with stronger infrared absorption and longer atmospheric lifetime,» say the authors.

The global warming potential (GWP) depends on both the efficiency of the molecule as a greenhouse gas and its atmospheric lifetime.

The release of this trapped methane is a potential major outcome of a rise in temperature; it is thought that this is a main factor in the global warming of 6 °C that happened during the end - Permian extinction as methane is much more powerful as a greenhouse gas than carbon dioxide (despite its atmospheric lifetime of around 12 years, it has a global warming potential of 72 over 20 years and 25 over 100 years).

Further, translating regional sulfate emission into global forcing isnt really appropriate, since atmospheric sulfate has too short of an atmospheric lifetime (owing to cloud and rain processes) to influence the global radiation balance.

CH4 is relatively short - lived in the atmosphere (atmospheric lifetime on the order of a decade) relative to CO2 (atmospheric lifetime on the order of centuries) and therefore has a higher global warming potential over the shorter 20 - year time horizon (86 versus 34; Myhre et al. 2013).

It has atmospheric lifetime figures as well as global warming potentials for different elements of the atmosphere.

Deep cuts in carbon dioxide emissions are urgently needed to prevent dangerous climate change, but they must be complemented by reductions in short - lived climate pollutants, which produce a strong global warming effect but have relatively brief atmospheric lifetimes.

For example, if the CH4 abundance increases above its present - day value due to a one - time emission, the time it takes for CH4 to decay back to its background value is longer than its global unperturbed atmospheric lifetime.

Because of its short atmospheric lifetime, the scientists suggested that reducing soot could provide a quick, effective way to slow global warming in the short - term.

The global warming potential (GWP) depends on both the efficiency of the molecule as a greenhouse gas and its atmospheric lifetime.

Methane has an atmospheric lifetime of about 12 years and a global warming potential of 28 over a hundred - year period.
