Results obtained with a time-dependent 1-D model based on CFC-113 global emission rates evaluated by Wuebbles (1983, PhD Thesis, University of California; Lawrence Livermore Laboratory Report UCRL-53423) are in good agreement with our measured distribution....
c, Hemispheric differences measured for CFC-113. Multiple CCM simulation results appear in a, b, and c for CFCs as thick dark lines and are updated only annually; they represent simulations using the CAMCHEM model with MERRA2 reanalysis meteorology and the three-box-derived emission history. ...
3, similar time- and compound-dependent patterns are derived for neighbouring eastern Asian regions and confirms that a precise spatial attribution of these regional emission changes is prevented by the large distance between MLO and eastern Asia. In samples collected at MLO having enhanced surface ...
Emission profiles from the foam and refrigeration sectors comparison with atmospheric concentrations. Part 1: Methodology and data Methane, Nonmethane Hydrocarbons, Alkyl Nitrates, and Chlorinated Carbon Compounds including 3 Chlorofluorocarbons (CFC-11, CFC-12, and CFC-113) in Whole-......

2.4. Emission Modelling Global annual emissions of CFC-216ba, CFC-216ca and HCFC-225ca were derived using a 2D atmospheric chemical transport model. The model has 24 latitudinal bands and 12 vertical levels between 0 and 24 km altitude (see [23] for further details). The emissions were imp...

The study provides evidence that European CH 4 , CCl 2 F 2 and CCl 3 F emission have already declined to about one-third of 1987 levels by the end of 1990. Over the same period, no evidence of any phase-out in the European usage of methyl chloroform and CFC-113 was detected. 展开...
