Comparison Of Atmospheric Chemical Mechanisms For Regulatory And Research Applications
Four general types of chemical mechanisms that are used in atmospheric chemistry models are summarized, with a short description of the applications for which each type is most often used. Differences in the techniques used to develop these mechanisms can lead to some differences in their predictions of atmospheric pollutant concentrations. Three chemical mechanisms are used as an example to demonstrate how these predictions can differ both for absolute concentrations of pollutants and for their sensitivities of ozone and PM2.5 to emission reductions.
