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.

The CSIRO archive of Cape Grim Baseline Air Pollution Station - Hourly Atmospheric Meteorology datasets. 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. The role of the station has been to observe global air quality through the measurements of atmospheric pollution such as carbon dioxide, ozone, halocarbons, oxides of nitrogen, particulates, precipitation chemistry as well as to monitor other parameters such as solar radiation and meteorological variables. This archive contains hourly measurements of Atmospheric Wind speed and direction at 10 & 50m heights, temperature, humidity, rainfall, atmospheric pressure, number of baseline minutes for the hour, CN counts and carbon dioxide concentrations for the period from Jan 1976 until the present. Variable data is available as both an hourly averaged annual file or as a single (all years concatenated) file in either in Ascii (.dat) or binary (.bin) file format, including both Australian Eastern Standard Time (AEST) time and Co-ordinated Universal Time (UTC=AEST-10hr, also called GMT) time and date formats within each file.
