The North Slope of Alaska (NSA) atmospheric observatory at Utqiaġvik (formerly Barrow) provides data about cloud and radiative processes at high latitudes.
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.
In addition, from 2013 to 2021, ARM operated the third ARM Mobile Facility (AMF3) at Oliktok Point, east of Utqiaġvik.
