The Trinidad Head station is located atop Trinidad Head (elevation ~120 meters) on the remote north coast of California, approximately 30 km north of Eureka. The AGAGE operates two in-situ instruments there. The GC-MD instrument started measuring atmospheric CFC-11, CFC-12, CFC-113, CH₃CCl₃, CCl₄, N₂O, CH₄, and CHCl₃ in 1995. Air samples are collected from a tower used by the Coast Guard for marine VHF communications. A state of the art Medusa GC-MS instrument which can measure more than 40 trace gases, was installed in May 2005.
