The CSIRO Global Atmospheric Sampling Laboratory (GASLAB) Flask Sampling Network archive for the atmospheric trace gas hydrogen (H2) 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 for H2 concentrations are made through the use of a Gas Chromatograph with a mercuric oxide reduction gas detector “RGA3-1” (R1). 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.

The Cape Grim Baseline Air Pollution Station facility, located at the North/West tip of Tasmania (40° 41'S, 144° 41'E), is funded and managed by the Australian Bureau of Meteorology, with the scientific program being jointly supervised with CSIRO Marine and Atmospheric Research. This archive contains 1000 litre air samples contained in stainless steel flasks collected at approximately 3 monthly intervals since 1978. The archive is housed at the Aspendale laboratory of CSIRO Marine and Atmospheric Research. The Cape Grim air archive is invaluable in determining the past atmospheric composition of a wide range of gases. For some of these gases, accurate and precise analytical methods have only recently evolved (for example HFCs and PFCs). The measurements are state-of-the-art in precision and accuracy. They are used to identify trace gas trends in the Southern Hemisphere, which in turn can be used to drive climate change models and identify processes that influence changes to the atmosphere.

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.
