Selected analyses of air and rainwater chemistry and meteorological data are presented as part of the final efforts on the 5-year METROMEX study. The size characterization, air concentration, and source identification of aerosols over and near St. Louis are related to the urban-industrial activities of the metropolitan area. The precipitation studies are comprised of a comparison of chemical analyses of simulated rain samples between several laboratories, including the Survey. The results showed that the analytical technique used by the Survey for the chemical analysis of the METROMEX samples is excellent for increasing confidence in the published data. Other precipitation analyses are directed toward the acid rain problem as demonstrated by historical and current measurements in Illinois. The meteorological investigations consist of analysis of diurnal temperature and moisture cycles at urban and rural sites which relates to the development of the planetary boundary layer (PBL) as perturbed by the city. The three-dimensional character of the PBL is also presented as determined by the radiosonde operations during METROMEX. Finally, the technique to calculate three-dimensional trajectories of air motion using the numerous pilot balloon observations acquired during the project is presented. These data are essential for the full interpretation of the air and rain chemistry observations, and the development of empirical models of pollutant scavenging.
