- Atmospheric Dispersion Modeling Liaison Committee (ADMLC)
- ADMLC's main aim is to review current understanding of atmospheric dispersion for application in authorization or licensing of discharges to the atmosphere from industrial, commercial or other sites. ADMLC is concerned with long-term controlled releases as well as short-term releases, and at all scales, including on-site and within buildings.

- 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.

- U.S. EPA's Support Center for Regulatory Air Models
- The U.S. Environmental Protection Agency uses this site to provide information on the many dispersion models supporting regulatory programs required by U.S. law. All of the EPA's dispersion models and their Users' Manuals can be downloaded cost-free from here. An online forum is also provided for discussion/questions/answers on all aspects of the EPA's models.
