TL;DR: In this paper, an optimal estimation procedure for deriving the atmospheric lifetime of chlorofluorocarbon CFCl3 by using a nine-box two-dimensional model of the atmosphere is described.

TL;DR: The Atmospheric Lifetime Experiment (ALO) as mentioned in this paper was designed to determine accurately the atmospheric concentrations of the four halocarbons CFCl3, CF2Cl2, CCl4, and CH3CCl3 with emphasis on measurement of their longterm trends in the atmosphere.

TL;DR: In this article, the effects of release uncertainties on lifetime estimates were examined by studying fluorocarbon data for the 5-year period from July 1978-June 1983, and the lifetime estimates are updated using the trend technique and the annual global release rates of the gases are derived.

TL;DR: In this article, gas chromatographic determinations of the concentrations of CH3CCl3 at Adrigole (Ireland), Cape Meares (Oregon), Ragged Point (Barbados), Point Matatula (American Samoa), and Cape Grim (Tasmania) for the 3-year period July 1978 through June 1981 were presented.

TL;DR: In this article, the average mixing ratio of dichlorodifluoromethane in the lower troposphere is estimated to have been 285 pptv and to be increasing at 6.0%/year.
