CMAQ
CMAQ is an acronym for the Community Multi-scale Air Quality Model, a sophisticated atmospheric dispersion model developed by the US EPA to address regional air pollution problems. (For example, a multi-state area where ozone or fine particulate levels exceed the US health standards.) In addition to simulating the emission, advection, diffusion, and deposition of air pollutants, CMAQ treats a wide array of chemical reactions that occur throughout the lower atmosphere. For example, ozone forms in the atmosphere when nitrogen oxides interact with volatile organic compounds in the presence of sunlight. Ammonium sulfate is formed in fine particulate matter when sulfuric acid (formed largely in cloud water) interacts with gas-phase ammonia. Meteorological conditions such as subsidence inversion
