The Cape Grim Baseline Air Pollution Station (CGBAPS) was established by the Australian Government to monitor and study global atmospheric composition. The station is operated and managed by the Australian Bureau of Meteorology, with the science program being a joint responsibility between the Bureau and the Commonwealth Scientific and Industrial Research Organisation (CSIRO). The ALE/GAGE/AGAGE programs started measuring atmospheric CFC-11, CFC-12, CH₃CCl₃, CCl₄, N₂O in 1978, CFC-113 (1982), CH₄ (1986), and CHCl₃, CO and H2 all in 1993 by using high-precision GC-multidetector (GC-MD) system.

The first gas chromatograph-mass spectrometer (GC-MS), with adsorption-desorption system (ADS), was installed at the Cape Grim, Tasmania station in November 1997. This ADS GC-MS instrument was later retired in December 2004 and replaced by a new state of art Medusa GC-MS system that was installed and started operation in January 2004.
