Atmospheric transformations encompass both physical and chemical changes of chemicals in the atmosphere. Modeling atmospheric transformations include gas phase chemical reactions, phase transitions, aqueous phase reactions, and processes involved in the formation of ozone, particulate matter, hazardous air pollutants, and halogen chemistry.
The US EPA has devoted significant efforts to developing photochemical air quality models for the assessment of air pollution issues and evaluation of control strategies. The most common photochemical models are:
