Description:
An empirical analysis of ambient air quality data for the Los Angeles Basin is used to relate the one- and two-hour changes in oxidant levels in the urban environment to the preceding levels of precursor pollutants and to meteorological variables. The intent was to demonstrate the feasibility of developing a set of empirical difference equations for the production of oxidant over time. The main variables determining one- and two-hour oxidant changes were identified using nonparametric regression techniques. A model for the oxidant changes was developed using nonlinear regression techniques. the implications of the model are discussed.
