Stratospheric lifetimes of cfc-12, ccl4, ch4, ch3cl and n2o from measurements made by the atmospheric chemistry experiment-fourier transform spectrometer (ace-fts)... The long-term impact of these species on the ozone layer is dependent on their stratospheric lifetimes....

Gas phase spectra of hobr and br2o and their atmospheric significance... From the results of theatmospheric lifetime calculations for Br2O, it is clear that thismolecule has a short stratospheric lifetime and is not likely to have a largedaytime concentration, for example, 20 s (albedo of 25%, SZA of 20°and an altitude of 17 km), and 83 s (albedo and 25%,...

Uv absorption cross sections of nitrous oxide (n2o) and carbon tetrachloride (ccl4) between 210 and 350 k and the atmospheric implications... The new cross sections result in a 5-7% increase in the modeled CCl4 photolysis loss, and a slight decrease in the stratospheric lifetime, from 51 to 50 years, for present day conditions....

Global distributions of carbonyl sulfide in the upper troposphere and stratosphere... Using coincident ACE measurements of CFC-11 and CFC-12 we determine a global OCS stratospheric lifetime of 64 ± 21 years corresponding to a stratospheri

Emission location dependent ozone depletion potentials for very short-lived halogenated species... The ODPs are determined by the fraction of source gas and its degradation products which reach the stratosphere, depending primarily on tropospheric transport and chemistry, and the effect of the resulting reactive halogen in the stratosphere, which is determined by stratospheric transport and chemistry, in particular by stratospheric residence time....

Seasonal ventilation of the stratosphere: robust diagnostics from one-way flux distributions... From the one-way flux, we determine the mass of the stratosphere that is in transit since entry through the tropical tropopause to its exit back into the troposphere, partitioned according to stratospheric residence time and exit location....

Abstract tracer-independent approaches to stratosphere-troposphere exchange and tropospheric air mass composition... By partitioning the one-way flux across the thermal tropopause according to stratospheric residence time τ and the regions where air enters and exits the stratosphere, the one-way flux is quantified robustly without being rendered ill-defined by the short-τ...
