In recent years there has been an increasing recognition of the research needs for the performance evaluation of air quality simulation models AQSMs (diffusion models) in United States. Accordingly, in order to meet these needs a large number of studies were carried out: American Meteorological Society AMS workshop, US EPA's model evaluation program and Electric Power Research Institute EPRI plume model validation and development PMV & D project and so on.
Since a diffusion model for a large elevated point source in rural area was considered to be completed until early 1970's in some sectors of Japan, any improvement for these models of Japan in 1980's cannot be seen. However, more comprehensive and large scale projects in U.S. point out some contradictions in these models.
This review paper shows the recent progress of the development of the rural diffusion models and performance evaluation of a diffusion model for regulatory use.
