Basic meteorological support consisted of the application of dispersion models, and the conduct of dispersion studies and model evaluations. The primary research effort was the development and evaluation of air quality simulation models using numerical and physical techniques supported by field studies. Modeling emphasis was on the dispersion of photochemical oxidants and particulate matter on urban and regional scales, dispersion in complex terrain, and atmospheric processes related to the acid deposition problem. Highlights during FY-1985 included evaluation of the dividing streamline height concept for flow over and around terrain features, completion of the VALMET and MELSAR models for use in specific terrain situations; development of a preliminary version of the Regional Acid Deposition Model (RADM). 收起
