The northern tropical atmospheric research station at Ragged Point, Barbados is located on the eastern edge of the island with direct exposure to the Atlantic Ocean. It experiences generally easterly winds disrupted routinely by the passage of cyclones and anticyclones. The ALE/GAGE/AGAGE has operated continuously at this location since 1978. There are two in-situ instruments there. The GC-MD instrument started measuring atmospheric CFC-11, CFC-12, CH₃CCl₃, CCl₄ and N₂O in 1978, CFC-113 in 1985, and CH₄ and CHCl₃ in 1996. A state of the art Medusa GC-MS instrument, with capability of measuring more than 40 trace gases, was installed in May 2005.
