North Slope of Alaska

With the rapid changes in the arctic environment, the North Slope of Alaska (NSA) has become a focal point for atmospheric and ecological research. Since 1997, the Atmospheric Radiation Measurement (ARM) user facility has gathered climate data at its NSA site in Barrow, the northernmost city in the United States located on the edge of the Arctic Ocean. ARM established multiple climate research sites on the North Slope to provide data about Arctic clouds and precipitation.
