The Atmospheric Radiation Measurement (ARM) Program establishes and operates field research sites to study the effects of clouds on global climate change. Three primary locations—Southern Great Plains, Tropical Western Pacific, and North Slope of Alaska—were identified as representing the range of climate conditions that should be studied. Each site has been 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 permanent 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.
