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. {"type": "Point", "coordinates": [144.689, -40.683]} 144.689 144.689 -40.683 -40.683 Documentation Link documentDigital Link to Cape Grim Homepage HTML
