PROJECT / WFO-332 / ACTIVE
North Atlantic Observation Array
A distributed network measuring atmospheric, geomagnetic, timing, and environmental conditions across the North Atlantic.

NA-17 / SITE CONTEXT
Cadillac Mountain summit sector.
The public station coordinate, 44.3520° N / 68.2251° W, resolves to the summit area of Cadillac Mountain on Mount Desert Island. The field package is therefore represented on exposed granite with low summit vegetation and broad coastal visibility rather than in a generic wooded clearing.
