CSIRO GASLAB Flask Air Samples

CSIRO Oceans and Atmosphere - GASLAB discrete flask data from Antarctic/Sub-Antarctic sampling sites, which is part of a global sampling network. Air samples were collected in glass flasks at Casey (CYA), Mawson (MAA), and Macquarie Island (MQA) and analyzed at CSIRO Aspendale Laboratories for methane (CH4), carbon dioxide (CO2), nitrous oxide (N2O), hydrogen (H2), carbon monoxide (CO) and carbon 13 of CO2 (CO2C13).Sampling site details:CYA: Current Sampling Altitude(m): 55.0        Station Altitude:47.0        Intake Height:8.0MQA: Current Sampling Altitude(m): 13.0        Station Altitude:6.0        Intake Height:7.0MAA: Current Sampling Altitude(m): 42.0        Station Altitude:32.0        Intake Height:10.0Trace gas species:Species: CO2; Scale: WMOX2007 CO2 mole fraction scale; Units: parts per million (ppm) or micromoles per mole of dry air.Species: CH4; Calibration scale: WMO X2004A CH4 scale; Units: parts per billion (ppb) or nanomoles per mole of dry air.Species: CO; Calibration scale: CSIRO94 CO scale (derived from the scale maintained by NOAA/CMDL in 1991); Units: parts per billion (ppb) or nanomoles per mole of dry airSpecies: co2c13; Calibration scale: VPDB-CO2 scale (CSIRO2005) - units of per millSpecies: co2o18; Calibration scale: VPDB-CO2 scale (CSIRO2005) - units of per millSpecies: H2; Calibration scale: MPI 2009 H2 scale (Max Planck Institute, Germany); Units: parts per billion (ppb) or nanomoles per mole of dry airSpecies: N2O; Calibration Scale: NOAA 2006A N2O scale (National Oceanic and Atmospheric Administration, USA); Units: parts per billion (ppb) or nanomoles per mole of dry airContacts: [e-mail]        [e-mail]        [e-mail]        [e-mail]        [e-mail] further information and before using these data, please refer to the relevant README file accessible at :ftp://gaspublic:[e-mail]/pub/data/gaslabThis data is part of an integrated global greenhouse gas dataset maintained by the World Data Centre for Greenhouse Gases (http://ds.data.jma.go.jp/gmd/wdcgg/).The latest data update was provided on July 6, 2021.
