Station Description:

General Description:

The North Slope of Alaska (NSA) site is providing data about cloud and radiative processes at high latitudes. These data are being used to refine models and parameterizations as they relate to the Arctic.

The Barrow facility was dedicated in July 1997 and chosen because the Arctic is particularly sensitive to climate changes. Barrow is located at the northernmost point in the United States, 330 miles north of the Arctic Circle.

Station Operator:
