| The '''Air Resources Laboratory''' (ARL) is an [[air quality]] and [[climate]] laboratory in the [[Office of Oceanic and Atmospheric Research]] (OAR) which is an operating unit within the [[National Oceanic and Atmospheric Administration]] (NOAA). In October 2005, the Surface Radiation Research Branch of the ARL was merged with five other NOAA labs to form the [[Earth System Research Laboratory]]. | |
|
| |
|
| The Air Resources Laboratory (ARL) studies processes and develops models relating to climate and air quality, including the transport, [[Atmospheric dispersion modeling|dispersion]], transformation and removal of pollutants from the ambient atmosphere. The emphasis of the ARL's work is on data interpretation, technology development and transfer. The specific goal of ARL research is to improve and eventually to institutionalize prediction of trends, dispersion of [[Atmospheric dispersion modeling|air pollutant plumes]], air quality, atmospheric deposition, and related variables. | | The SPS was created to engage in [[meteorological]] research to assist the emerging atomic energy progams of the United States, much of which involved weapons testing. |
|
| |
|
| ARL provides scientific and technical advice to elements of NOAA and other Government agencies on atmospheric science, environmental problems, emergency assistance ([[United States Department of Homeland Security|Homeland Security]]), and [[climate change]].
| | The director of the SPS was Dr. Lester Machta who was joined by four other meteorologists. Initially, funding came from the [[Department of Defense]] and later from the [[Atomic Energy Commission]], the predecessor of the [[Department of Energy]]. A great deal of funding also came from outside financial support. |
|
| |
|
| ARL operates with research divisions in [[Idaho Falls, Idaho]]; [[Research Triangle Park|Research Triangle Park, North Carolina]]; [[Las Vegas, Nevada]]; [[Oak Ridge, Tennessee]]; and [[Silver Spring, Maryland]].
| | One of the most important contributions of the SPS was publication of the book ''Meteorology and Atomic Energy'' in 1968, edited by David H. Slade. That book summarized the state of the science about the [[Planetary Boundry Layer]] (PBL) processes and the applied meteorology of air pollution plume rise and dispersion, and turbulence and atmospheric stability. With contributions from SPS scientists and other experts, that book was the primary source of information about air pollution dispersion for many decades. |
|
| |
|
| ==The Atmospheric Sciences Modeling Division==
| | In the early years, the SPS was headquartered in [[Washington, DC]]. When the SPS became part of NOAA and was named the Air Resources Laboratory, the headquarters ended up in its current location in Silver Spring, Maryland. |
| | |
| The Atmospheric Sciences Modeling Division (ASMD) of the ARL was established in 1955 to collaborate with the [[United States Environmental Protection Agency|U.S. Environmental Protection Agency]] (EPA) and its predecessor agencies in developing advanced air quality models that can simulate the formation, transport, dispersion and fate of pollutants in the atmosphere. The ASMD develops advanced modeling and decision support systems for effective forecasting and management of the air quality in the United States. The Division is located in [[Research Triangle Park|Research Triangle Park, North Carolina]].
| |
| | |
| 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, as affected by changes in ecosystem management and regulatory decisions. 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 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.
