The CSIRO Global Atmospheric Sampling Laboratory (GASLAB) Flask Sampling Network archive for the atmospheric trace gas nitrous oxide (N2O) concentrations. GASLAB principally analyzes air samples that have been captured at eleven fixed geographic sites and one moving (aircraft over bass strait and Cape Grim), but also includes other sites at various locations globally on a less regular or as needed basis. The flask air sample is analyzed for the 5 atmospheric trace gases Methane (CH4), Carbon Dioxide (CO2), Carbon Monoxide (CO), Hydrogen (H2) and N2O (Nitrous Oxide). Data about the relative concentrations of these are particularly important for Global Warming studies as CO2 and CH4 are the two most effective anthropogenic greenhouse gases; CO and H2 influencing concentrations of the hydroxyl radical (OH), thereby affecting the main sink for atmospheric CH4. H2 is produced in a sequence of reactions following the reaction of OH with CH4. Measurements of N2O concentrations are made through the use of a Gas Chromatograph with electron capture detection (ECD), “Shimadzu-1” (S1). There are 6 differant types of flask that are used to store and transport air samples from site and in the labratory:(i) glass 0.5 litre ("G050"), (ii) glass 5.0 litre ("G500"), (iii) glass 0.8 litre ("G080"), (iv) electropolished stainless steel 1.6 litre "Sirocans" ("S160"), (v) glass 2.0 litre, 1 stopcopck ("F", "FF", "FA", "FE", "EP", ALT"), (vi) glass 2.0 litre, 2 stopcocks(“M1”, “S”, “P2”, “TEMP”). Files containing a single species value for each sample are denoted by a filename of the form (XXX_XXXX_event.XXX), for the geographically fixed sites data is also provided in the form of monthly means (e.g. XXX_XXXX_mm.XXX) with all fies being in ascii format.

This collection includes ice cores and associated air samples from Antarctica and Greenland. Ice cores are collected from various sites including Law Dome Antarctica. Data files are kept on depth, age, chemical composition and gas compositions of the ice cores. The ice cores samples are archived and stored at Breeze Logistics (Cold Storage), Clayton, VIC. These samples are part of a series including Australian Antarctic Division Ice Cores (Hobart)and Greenland Ice Cores (Copenhagen). The data associated with this collection can be accessed through the World Data Center(WDC) for Paleoclimatology http://www.ngdc.noaa.gov/wdc/usa/paleo.html.

The CSIRO archive of the Advanced Global Atmospheric Gases Experiment (AGAGE) datasets. The AGAGE project is part of the powerful global observing system that has been continuously measuring the composition of the atmosphere at high frequency from chosen coastal sites around the world, providing accurate measurements of trace gases whose lifetimes are long compared to global atmospheric circulation times. This particular dataset represents measurements taken utilizing GC-MD (Gas Chromatograph Multiple Detector) type of instrumentation which contains Electron Capture Detectors (ECD), Flame Ionization Detector (FID) & Mercuric oxide Reduction Detector (MRD). Utilising these it is possible to accurately measure the five biogenic/anthropogenic gases (CH4,N2O,CHCl3,CO & H2) and five anthropogenic gases (CCl3F, CCl2F2, CH3CCl3, CCl2FCClF2 & CCl4). This coupled with the GC-MS dataset covers almost all of the important trace gas species in the Montreal Protocol (e.g. halocarbons such as bromocarbons, CFCs and HCFCs) to protect the ozone layer and almost all of the significant non-CO2 gases in the Kyoto Protocol (e.g. HFCs, methane, and nitrous oxide) to mitigate climate change. AGAGE is the expansion and continuation of the Atmospheric Life Experiment(ALE) 1978-1981 and the Global Atmospheric Gases Experiment(GAGE) 1981-1985. Participating AGAGE stations include Cape Grim (Tasmania), Mace Head (Ireland), Ragged Point (Barbados), Cape Matatula (Samoa) & Trinidad Head (California), with urban stations at SIO (La Jolla, California) and CMAR(Aspendale, Australia). Data is available in yearly files either in Ascii (.C), Ascii decimal date(.C.Dat) or binary file format(.bin). It is also available in a processed form (Courtesy of the Georgia Institute of Technology) to include a Polluted data flag in the decimal date version only. AGAGE also collaborates with the System for Observation of Halogenated Greenhouse Gases in Europe (SOGE), through transfer of AGAGE calibrations and sharing of AGAGE technology, placing AGAGE and SOGE data on common calibration scales with comparable precisions, accuracy and measurement frequency. Soge contributing stations are Monte Simone (Italy), Jungfraujoch (Switzerland), & Ny-Alesund-zeppelin (Norway). AGAGE's network also includes Hateruma Island Japan through a co-operative agreement with the Japanese National Institute for Environmental Studies (NIES). The other two collaborative stations are at Shangdianzi, China and Gosan, Jeju Island, South Korea. Shangdianzi started measuring ozone-depleting trace gases and greenhouses gases in 2006, and is a part of SOGE-A project. The Gosan station, started in late 2007, is operated by Seoul National University (SNU).

This record describes the atmospheric greenhouse data acquired by a continuous wave Quantum Cascading Laser (QCL) analyser (QC-TILDAS, Aerodyne Research Inc., USA) collected on the Marine National Facility RV Investigator Event voyage IN2015_E01. This is a trial voyage for the RV Investigator departing Hobart on the 29 Jan 2015 and returning to Hobart on the 19 Feb 2015. It is an atmospheric greenhouse gas analyser for measuring nitrous oxide, carbon monoxide and water vapour in air. This instrument is an MNF procurement. The air is partially dried with a refrigerated dryer (5oC) to avoid potential condensation in the sample lines, valve and instrument. Measurements are extrapolated to dry air mole fractions. Calibrations are conducted pre and post each voyage and at a monthly interval for extended voyages. Calibrations are conducted in-situ with three calibrated air standards. An automated daily reference gas sample is also conducted (15 minutes).
