CSIRO GASLAB Flask Air Samples

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:8.0 MQA: Current Sampling Altitude(m): 13.0 Station Altitude:6.0 Intake Height:7.0 MAA: Current Sampling Altitude(m): 42.0 Station Altitude:32.0 Intake Height:10.0 Trace 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 air Species: co2c13; Calibration scale: VPDB-CO2 scale (CSIRO2005) - units of per mill Species: co2o18; Calibration scale: VPDB-CO2 scale (CSIRO2005) - units of per mill Species: H2; Calibration scale: MPI 2009 H2 scale (Max Planck Institute, Germany); Units: parts per billion (ppb) or nanomoles per mole of dry air Species: N2O; Calibration Scale: NOAA 2006A N2O scale (National Oceanic and Atmospheric Administration, USA); Units: parts per billion (ppb) or nanomoles per mole of dry air Contacts: david.etheridge@csiro.au paul.steele@csiro.au paul.krummel@csiro.au ray.langenfelds@csiro.au marcel.vanderschoot@csiro.au For further information and before using these data, please refer to the relevant README file accessible at : ftp://gaspublic:gaspublic@ftp.dar.csiro.au/pub/data/gaslab This data is part of an integrated global greenhouse gas dataset maintained by the World Data Centre for Greenhouse Gases (ds.data.jma.go.jp/gmd/wdcgg/).
