Barrow Baseline Observatory
Reference CryoNet Station Information

Barrow, Alaska Observatory (BRW), established in 1973, is located on the northern most point of the United States. It is about 8 km northeast of the village of Barrow and has a prevailing east-northeast wind off the Beaufort Sea. In addition, the National Weather Service (NWS) maintains a weather observing facility in Barrow. Although the measurements at Barrow are made over open tundra, there are large lagoons and a number of lakes in the vicinity, and the Arctic Ocean is less than 3 km northwest of the site. Because of its proximity to these bodies of water and the fact that the prevailing winds are off the Beaufort Sea, BRW is perhaps best characterized as having an Arctic maritime climate affected by variations of weather and sea ice conditions in the Central Arctic.

This facility is manned year round by 2 engineers/scientists to complete routine inspections and maintenance of the instruments. Due to its unique location, dedicated and highly trained staff, and excellent power and communications infrastructure, the Barrow Observatory is host to numerous cooperative research projects from around the world.

Measurement Notes and Other Measurements

Category Description or List
PermafrostSoil temps measured in top 120cm (covering the active layer). From this, other parameters can be easily calculated. Not currently a data product.
