description The station is located approximately 50m from the coastline on a raised 30m x 30m platform built on top of lava rock. There are no habitations within a 2 km radius; the nearest public road is 1.2 km downwind. The prevailing wind is from the NE from the open ocean bringing airmasses from the tropical Atlantic and from the African continent. The main laboratory is housed in a converted 40ft shipping container, with a second 20ft container for ancillary use. A 10m mast and 30m scaffold tower are used for instrument inlets.
