Climate Forcing at the Arctic LTER Site
The Arctic LTER site is located at 68º38'N and 149º43'W, at an elevation of 760 m in the northern foothills of the Brooks Range, Alaska. The location, 208 km south of Prudhoe Bay, was chosen for accessibility to the Dalton Highway, which extends along the Trans-Alaska Oil Pipeline from nor...
