| Abstract |
Data from the Regional Air Pollution Study are surveyed to delineate the experience with NO and NO2 concentrations in St. Louis, a metropolitan area in the central United States. Two-year time series are produced for the daily maximum 1-h average in the monitoring network and the 24-h average of central urban sites. Various aspects of the data are displayed graphically including the time and location of the maximum, the distribution of concentration, and the relation of high concentrations to meteorological factors. A stagnation episode is examined in detail, and predictions of an air quality model are compared with measured levels of O3, NO, NO2, and CO. |
