About ARL

The Air Resources Laboratory’s (ARL) mission is to improve the ability of the Nation to protect human and ecosystem health and to support a vibrant economy through advanced atmospheric sciences and technologies. ARL’s research focus is on the surface of the earth from a few feet below the soil up to 2-3 miles in the atmosphere (aka the boundary layer), which has a direct impact on people’s health and safety, business, and the environment. ARL studies the physical and chemical processes that occur in the boundary layer, on time scales spanning a few hours to several years.

ARL studies the mixing, exchange, and transformation of energy, moisture, trace gases, and particles, and contributes inputs to meteorological models and forecast operations that are vital in improving weather, climate and air quality forecasts. Primary applications include emergency response, homeland security, air quality, weather forecasts and climate outlooks, and commerce and transportation. ARL’s vision is to effectively protect people, the environment, and commercial activities from atmospheric risks using the best available scientific understanding of boundary layer processes.

The Atmospheric Turbulence and Diffusion Division (ATDD) celebrated the Air Resources Laboratory’s (ARL) 75th anniversary with an Open House that brought together NOAA leadership, local policy-makers, and ARL partners. One of the projects introduced was the U.S. Climate Reference Network, or USCRN. This is a project ATDD has been involved with, along with our partners from NOAA’s National Centers for Environmental Information (NCEI), since its initial design in the late 1990s and implementation which began in 2002.

ARL continues its 75th anniversary celebrations with an open house at ATDD in Oak Ridge, TN.
