# file: global_F113_MM.dat # # Atmospheric measurements of Cl2FC-CClF2 (CFC-113, Freon-113, F113) # # Measurements are from the NOAA/ESRL/GMD/HATS flask program # (http://www.esrl.noaa.gov/gmd/hats/flask/flasks.html). # Instrument ID: Otto # # Location: Global -- Monthly Global-Hemispheric Means # See http://www.esrl.noaa.gov/gmd/dv/site/site_table.html#hats_flask for # more information about flask sampling sites. # # The data reported are from samples collected approximately once per week in # matching, concurrent, flask pairs and later analyzed on a gas chromatograph # with electron capture detection (GC-ECD) located in Boulder, Colorado, USA. # This system uses two standard reference gases for calibration and has been # in operation since very early in 1995. # # These data represent monthly global and hemispheric mean estimates computed # using data from the monthly companion files named *_F113_MM.dat, where * # refers to a 3-character baseline site code. For any given month in the more # recent period, data from as many as 12 sites may be used to derive the global # mean, including as many as 4 sites in the southern hemisphere and up to 8 in # the northern hemisphere. From north to south, these baseline sites include # ALT, SUM, BRW, MHD, THD, NWR, MLO, KUM, SMO, CGO, PSA, and SPO: # # ALT - Alert, Canada 82.45 N 62.51 W 190 m # SUM - Summit, Greenland 72.60 N 38.42 W 3209 m # BRW - Barrow, Alaska 71.32 N 156.61 W 11 m # MHD - Mace Head, Ireland 53.33 N 9.90 W 5 m # THD - Trinidad Head, California 41.05 N 124.15 W 107 m # NWR - Niwot Ridge, Colorado 40.05 N 105.59 W 3523 m # MLO - Mauna Loa, Hawaii 19.54 N 155.58 W 3397 m # KUM - Cape Kumukahi, Hawaii 19.52 N 154.82 W 3 m # SMO - Tutuila, Samoa 14.25 S 170.56 W 42 m # CGO - Cape Grim, Tasmania 40.68 S 144.69 E 94 m # PSA - Palmer Station, Antarctica 64.92 S 64.00 W 10 m # SPO - South Pole, Antarctica 89.98 S 24.80 W 2810 m # # The global and hemispheric uncertainties reported here are bootstrapped from # 1000 'resamples' of the input monthly means drawn in accordance with the # uncertainties reported in the companion files. # # PIs: Dr. James W.
