The Air Resources Laboratory (ARL) is an air quality and climate laboratory in the Office of Oceanic and Atmospheric Research (OAR) which is part of the National Oceanic and Atmospheric Administration (NOAA).

ARL has divisions in Idaho Falls, Idaho; Research Triangle Park, North Carolina; Las Vegas, Nevada; Oak Ridge, Tennessee; and Silver Spring, Maryland.

Overview of the ARL's Responsibilities

ARL develops models relating to climate and air quality, including the transport, dispersion, transformation and removal of pollutants from the ambient atmosphere. The emphasis of the ARL's work is on technology development and transfer. The specific goal of ARL research is to improve prediction of trends, dispersion of air pollutant plumes, air quality, atmospheric deposition, and related subjects.

ARL provides scientific and technical advice to other groups within NOAA and other government agencies on atmospheric science, environmental problems, emergency assistance, and climate change. Much of the ARL's work is done by the Atmospheric Sciences Modeling Divison of the ARL.

The Atmospheric Sciences Modeling Division

The Atmospheric Sciences Modeling Division (ASMD) is part of the ARL. The ASMD develops and evaluates predictive atmospheric models on all spatial and temporal scales for forecasting air quality and for assessing changes in air quality and air pollutant exposures. It was established in 1955 to collaborate with the United States Environmental Protection Agency (EPA) and its predecessor agencies in developing advanced air quality models. The ASMD currently works in a partnership with the EPA and is located in Research Triangle Park, North Carolina.

The ASMD's responsibilities

The ASMD is responsible for providing a sound scientific and technical basis for regulatory policies to improve ambient air quality. The air quality and pollution dispersion models developed by the ASMD are being used by the EPA, NOAA, and the general air pollution community in understanding and forecasting not only the magnitude of the air pollution problem, but also in developing emission control policies and regulations.
