NOAA's Air Resources Laboratory (ARL)

NOAA's Air Resources Laboratory (ARL)- Within the U.S.'s National Oceanic and Atmospheric Administration (NOAA), the ARL conducts research on the transport, dispersion, transformation, and removal of atmospheric pollutants - leading to the development of air quality and dispersion models. The ARL also supports other U.S. agencies. In particular, the ARL's Atmospheric Turbulence and Diffusion Division (ATTD) and Atmospheric Sciences Modeling Division (ASMD) support the U.S. EPA in developing regulatory air dispersion models.
