Sites

The ARM Climate Research Facility establishes and operates field research sites to study the effects of aerosols, precipitation, surface flux, and clouds on global climate change. Three primary locations—Southern Great Plains, Tropical Western Pacific, and North Slope of Alaska—represent the broad range of climate conditions around the world. ARM sites at these locations are heavily instrumented to gather massive amounts of climate data. Using these data, scientists are studying the effects and interactions of sunlight, radiant energy, and clouds to understand their impact on temperatures, weather, and climate.

In addition to our fixed facilities, the ARM Mobile Facility is designed to obtain atmospheric measurements similar to those at the other ARM sites for periods up to a year at a time anywhere in the world. The ARM Aerial Facility obtains aerial measurements above fixed ARM sites and AMF deployments. These measurements contribute to specific science questions proposed by the ARM Science Team and the external research community.

In 2013, ARM added two new sites—an extended deployment of a new mobile facility at Oliktok Point, Alaska, and a new fixed site in the Eastern North Atlantic near the 2009-2010 Graciosa Island site in the Azores.
