Chlorofluorocarbon production scenarios: possible changes to stratospheric ozone
As one aspect of the regulatory process, the Environmental Protection Agency has derived a series of scenarios for future atmospheric emission rates of the chlorofluorocarbons CFCl/sub 3/ (also referred to as F-11), CF/sub 2/Cl/sub 2/ (F-12), CCl/sub 2/FCClF/sub 2/(F-113), CClF/sub 2/CClF/sub 2/(F-114), and CClF/sub 2/CF/sub 3/ (F-115). These scenarios are based on potential industrial production and commercial applications, and the eventual release of these chemicals into the atmosphere. In this study, the potential effect on stratospheric ozone resulting from future chlorofluorocarbon emissions as suggested by these scenarios is examined. Assessments are based upon model calculations using the one-dimensional coupled transport and chemical kinetics model of the troposphere and stratosphere developed at Lawrence Livermore National Laboratory. The change in total ozone column calculated for the seven scenarios as a function of time is given. (JGB)
