Description
Cape Grim Observatory is an internationally reknown baseline station with many ongoing local and international cooperating programs. The site is located at the north-west corner of Tasmania, Australia and has predominant westerly winds that make it ideal for sampling of unpolluted air. The station is permanently staffed with about eight officers plus temporary staff, and has about 14 lead scientists for the local projects.
