The development of the acid deposition and oxidant model (ADOM).

This paper describes the development and testing of the Acid Deposition and Oxidant Model (ADOM), a nine-year project funded by a consortium consisting of Environment Ontario, Environment Canada, the German Umweltbundesamt, and the Electric Power Research Institute. The project consisted of three major phases: a design phase, an implementation phase, and an evaluation phase. In the design phase, the system being modeled was divided into its components-transport, gas phase chemistry, aqueous phase chemistry, dry deposition and cloud processes.
