Summary
Abstract:
The National Oceanic and Atmospheric Administration's (NOAA) Climate Monitoring and Diagnostics Laboratory (CMDL) has collected chlorofluorocarbon (CFC) and nitrous oxide (N2O) from flask samples and in situ instruments located at monitoring stations. The Halocarbons and other Trace Species Group (HATS) of NOAA/CMDL collects measurements for a standard suite of Radiatively Important Trace Species ... (RITS): CFC-12, CFC-11, CFC-113 (1,1,2-trichlorotrifluoroethane), methyl chloroform (MC), carbon tetrachloride (CT) and nitrous oxide (N2O). NOAA/CMDL/HATS stations are at Point Barrow, Alaska (BRW); Mauna Loa, Hawaii (MLO); Cape Matatula, American Samoa (SMO); and, South Pole, Antarctica (SPO). Cooperative stations are at Niwot Ridge, Colorado (NWT); Alert, Canada (ALT); and Cape Grim, Australia (CGO). Starting in 1977, paired samples were collected each week in electropolished stainless steel flasks at the four NOAA/CMDL/HATS sites and Niwot Ridge. After 1980, flask pairs at South Pole were collected once a week. Collection of flask pairs at Alert bagan in 1988 and at Cape Grim in 1991. All flasks were shipped back to NOAA/CMDL in Boulder, CO for analysis by electron capture gas chromatography (EC-GC). In 1987 the flask sample program was complemented by automated in situ measurements at the four NOAA/CMDL/HATS sites and Niwot Ridge. Principal investigators for the CFC-11 and CFC-12 in situ and flask measurements are: J. Elkins, T. Thompson, and J. Butler (NOAA/CMDL) Principal investigators for the CFC-113 flask measurements are: S. Montzaka, J. Elkins, and J. Butler (NOAA/CMDL) The NOAA/CMDL data are available via anonymous ftp as follows: ftp://ftp.cmdl.noaa.gov/hats/ or ftp://ftp.cmdl.noaa.gov/hats/cfcs ftp://ftp.cmdl.noaa.gov/hats/n2o The following datasets are currently available via ftp: Monthly in situ CFC-11 data from BRW, MLO, NWR, SMO and SPO. Hourly in situ CFC-11 data from BRW, MLO, NWR, SMO and SPO. Daily in situ CFC-11 data from BRW, MLO, NWR, SMO and SPO. Monthly global flask CFC-11 data. Monthly flask pairs CFC-11 data from ALT, BRW, CGO, MLO, NWR, SMO, and SPO. Monthly in situ CFC-12 data from BRW, MLO, NWR, SMO and SPO. Hourly in situ CFC-12 data from BRW, MLO, NWR, SMO and SPO. Daily in situ CFC-12 data from BRW, MLO, NWR, SMO and SPO. Monthly global flask CFC-12 data. Monthly flask pairs CFC-12 data from ALT, BRW, CGO, MLO, NWR, SMO, and SPO. Monthly flask pairs CFC-113 data from ALT, BRW, NWR, MLO, SMO, CGO, and SPO. Monthly global N2O data.
