The Air Resources Laboratory (ARL) mission is to improve the ability of our Nation to protect human and ecosystem health and to support a vibrant economy through advanced atmospheric sciences and technologies. ARL’s research focus area is on the surface of the earth from one meter below the soil up to 2,000 meters in the atmosphere (aka the boundary layer), which has a significant impact on people’s health and safety, business, and the environment. ARL studies the physical and chemical, short- and long-term processes that occur in the boundary layer. In particular, ARL deals with the mixing, exchange, and transformation properties of energy, moisture, trace gases, and particles, and in contributing inputs to meteorological models and forecast operations that are vital in improving weather forecasts. Primary applications include emergency response, homeland security, air quality, weather forecasts and climate outlooks, and commerce and transportation. ARL’s vision is that the Nation effectively protects people, the environment, and commercial activities from atmospheric risks from a variety of scientific disciplines.
