Scientists at the Air Resources Laboratory (ARL) conduct research to gain new insights into atmospheric dispersion, atmospheric chemistry, climate change, and the complex behavior of the atmosphere near the Earth's surface, called the atmospheric boundary layer.

Our work provides needed atmospheric information and tools to decision-makers and to the science community to improve the Nation's ability to protect human health and the environment.

ARL is a research laboratory of NOAA's Office of Oceanic and Atmospheric Research. We are headquartered in College Park, Maryland and have divisions in Oak Ridge,Tennessee (ATDD); Idaho Falls, Idaho (FRD); and Las Vegas, Nevada (SORD).
