Chlorofluorocarbon-11, -12, and nitrous oxide measurements at the NOAA/GMCC baseline stations (16 September 1973 to 31 December 1979)
Details:
  • Description:
    Time-dependent atmospheric chlorofluorocarbon-11 (CCl₃F), chlorofluorocarbon-12 (CC₂F₂), and nitrous oxide (N₂O) measurement data are presented for five stations of the NOAA/ERL Air Resources Laboratory's Geophysical Monitoring for Climatic Change (GMCC) program. They include (1) CCl₃F data for September 1973 through December 1979 for Point Barrow, Alaska; Mauna Loa, Hawaii; and American Samoa, South Pacific; (2) CCl₃F data for early 1976 through December 1979 for Niwot Ridge, Colorado, and for early 1977 through December 1979 for South Pole, Antarctica; (3) CCl₂F₂ data for early 1977 through December 1979 for all stations; and (4) N₂O data for early 1977 through December 1979 for all stations. Details of the sampling and analysis program are presented as well. Statistical and meteorological data selection criteria are applied to the raw data to improve data quality. The improved data sets should be useful in studies of atmospheric CCl₃F, CCl₂F₂, and N₂O meridional distributions, mixing ratios, global abundances, growth rates, interhemispheric exchange rates, and tropospheric residence times.
