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.
