The North Slope of Alaska (NSA) atmospheric observatory is providing data about cloud and radiative processes at high latitudes. This observatory includes a central facility at Barrow (known officially as Utqiaġvik) and, to the east, the third ARM Mobile Facility at Oliktok Point.
The NSA is a focal point for atmospheric and ecological research activity in the Arctic. Scientists use data from the NSA to improve the representation of high-latitude cloud and radiation processes in earth system models.
