The Dr. Neil Trivett Global Atmosphere Watch Observatory is an atmospheric baseline station operated by Environment and Climate Change Canada located about 6 km (3.7 mi) south south-west of Alert, Nunavut, on the north-eastern tip of Ellesmere Island, about 800 km (500 mi) south of the geographic North Pole.
The observatory is the northernmost of 31 global stations in an international network coordinated by the World Meteorological Organization (WMO) under its Global Atmosphere Watch (GAW) program to study the long-term effects of pollution on the atmospheric environment.[1] Among these 31 stations, Alert is one of three greenhouse gas "intercomparison supersites",[2] along with Mauna Loa in Hawaii and Cape Grim in Australia, which, due to their locations far from industrial activity, provide the international scientific community with a baseline record of atmospheric chemistry.
