Mace Head Research Station is located on the west coast of Ireland, County Galway. The site offers excellent exposure to the North Atlantic (clean air sector, 180° through west to 300°). The nearest major conurbation approximately 90 km to the east of Mace Head is Galway, a city with a population of approximately 65000 inhabitants. The hilly area around Mace Head is wet and boggy with a lot of exposed rock and vegetation which consists mainly of grasses and sedges. There are three small uninhabited islands offshore which are within the clean air sector. The facilities at the site consist of three laboratory buildings, two aluminium walk-up towers, (20m and 10m) and a converted 20 ft cargo container office. The two shore laboratories, ca. 90m from the shore, house gas and aerosol measurement equipment. The cottage laboratory, ca. 300m from the shore primarily houses equipment for measurement of meteorlogical and solar radiation parameters.
