The National Oceanic and Atmospheric Administration's Air Resources Laboratory (NOAA/ARL) began measuring chlorofluorocarbon-11 in 1973 because of the interest in this anthropogenic pollutant as a tracer for the study of mass transfer processes in the atmosphere and the oceans. Interest in chlorofluorocarbon-11, and in chlorofluorocarbon-12 and nitrous oxide, was heightened during the mid-1970's with the realization that these compounds can be decomposed by photolysis in the stratosphere to cause stratospheric ozone destruction by released chlorine atoms. Measurements of chlorofluorocarbon-12 and nitrous oxide were begun by NOAA/ARL in 1977. The report describes the evolution of the chlorofluorocarbon and N/sub 2/O measurement programs through 1979. By that time, the sample collection and analysis techniques became standardized, and have remained the same to the present.
