Summary
Abstract:
Monthly atmospheric methane (CH4) concentrations were obtained from 35 globally distributed monitoring sites as part of the National Oceanic and Atmospheric Administration's Climate Diagnostic Monitoring Laboratory (NOAA/CMDL). Data were collected in glass flasks and methane concentrations were determined by gas chromatography. The data records represent methane concentrations for the modern ... period from 1983 to 1992. The 35 monitoring site records are as follows: 1) Alert, Northwest Territories, Canada (1985-1992) 2) Amsterdam Island, Indian Ocean (1983-1990) 3) Ascension Island (UK), South Atlantic Ocean (1983-1992) 4) Azores, Terceira Island, North Atlantic Ocean (1983-1992) 5) Barbados, (Ragged Point), Atlantic Ocean 6) Barrow, Alaska (1983-1992) 7) Bermuda (East, St. David's Head) (1989-1992) 8) Bermuda (West, Southhampton) (1989-1992) 9) Cape Grim, Tasmania, Australia (1984-1992) 10) Cape Kumukahi, Hawaii (1983-1992) 11) Cape Meares, Oregon (1983-1992) 12) Christmas Island, South Pacific Ocean (1984-1992) 13) Cold Bay, Alaska (1983-1992) 14) Guam, Mariana Islands, Pacific Ocean (1983-1992) 15) Halley Bay, Antarctica (1983-1991) 16) Izana, Canary islands, Spain (1991-1992) 17) Key Biscayne, Florida (1983-1992) 18) Mace Head, County Galway, Ireland (1991-1992) 19) Mauna Loa, Hawaii (1983-1992) 20) Midway Islands (Sand Island), Pacific Ocean (1985-1992) 21) Mould Bay, Northwest Territories, Canada (1983-1992) 22) Niwot Ridge, Colorado (1983-1992) 23) Olympic Peninsula, Washington (1985-1990) 24) Pacific Ocean, Ships Welligton Star and Southland Star (1986-1992) 25) Palmer Station, Antarctica (1983-1992) 26) Qinghai Province, Peoples Republic of China (1991-1992) 27) American Samoa (Cape Matatula), Pacific Ocean (1983-1992) 28) Seychelles (Mahe Island), Indian Ocean (1983-1992) 29) Shemya Island, Alaska (1985-1992) 30) South Georgia Island, Atlantic Ocean (1989-1991) 31) South Pole, Antarctica (1983-1992) 32) Ocean Station 'M', North Atlantic Ocean (1983-1992) 33) Syowa Station, Antarctica (1986-1992) 34) Tae-ahn Peninsula, South Korea (1991-1992) 35) Virgin Islands (St. Croix) (1983-1990) Data from all 35 sites are tabulated in the Carbon Dioxide Information Analysis Center's (CDIAC's) 'Trends '93: A Compendium of Data on Global Change' (Bod et al, eds., 1991) as monthly methane concentrations in parts per billion by volume (ppbv). These data are also available electronically as Numeric Data Package NDP-038 (Steele and Lang, 1991) from CDIAC: ftp://cdiac.esd.ornl.gov/pub/ndp038 Data from individual flask samples may also be obtained from P. Lang or E. Dlugokencky at NOAA/CMDL, 325 Broadway, Boulder, CO 80303-3328 as given in Lang, et al. (1990a,b) Please use the following citation for this dataset: Dlugokencky, E.J., P.M. Lang, K.A. Masarie, and L.P. Steele. 1994. 'Atmospheric CH4 records from sites in the NOAA/CMDL air sampling network'. pp. 274-350. In T.A. Boden, D.P. Kaiser, R.J. Sepanski, and F.W. Stoss (eds.), 'Trends '93: A Compendium of Data on Global Change', ORNL/CDIAC-65. Carbon Dioxide Information Analysis Center, Oak Ridge National Laboratory, Oak Ridge, TN, USA. Global CH4 data from NOAA/CMDL are tabulated in the Carbon Dioxide Information Analysis Center's (CDIAC's) 'Trends '93: A Compendium of Data on Global Change' (Boden, et al, eds., 1994) as depth, year, and CH4 concentration (ppmv) and is available via ftp: ftp://cdiac.esd.ornl.gov/pub/trends93/ch4/ NOTE: The NOAA/CMDL measurements of atmospheric methane mixing ratios is available on the NOAA/CMDL anonymous FTP site for the period 1983-1992. The FTP site is located at ftp://ftp.cmdl.noaa.gov/ccg/ch4/flask or FTP to ftp.cmdl.noaa.gov and cd to /ccg/ch4/flask. CDIAC has provided an anonymous FTP area to all data files, retrieval codes, and descriptive files for all data available in CDIAC's anonymous FTP in pub/trends93/ch4. The FTP address is CDIAC.ESD.ORNL.GOV and 128.219.24.36 and input your email address as the password. The data bases are arranged as subdirectories in /pub/trends93/ (co2, ch4, trace, emiss, precip, and temp) that correspond to major chapter headings in Trends '93. The data files are arranged as xxxxx.yyy where xxxxx is the name of the station, country, site, region, or principle investigator and yyy is the page number in Trends '93 (example: vostok.231 refers to the Vostok ice core dataset as tabulated on page 231.
