This report covers the data analysis and model development work performed to create and validate ELSTAR (Environmental Lagrangian Simulator of Transport and Atmospheric Reactions), a photochemical trajectory model for the prediction of ozone and nitrogen dioxide concentrations. Data from the Los Angeles Reactive Pollutant Program (LARPP), an extensive field program initiated to provide a meteorological and air quality data base for trajectory model development, were used both in developing and testing ELSTAR. The LARPP data base was found to be ideal for the development of such a trajectory model. Included in the report is a description of the stepwise development and testing of the model, a discussion of the test results, recommendations for future field programs, a discussion of the model's limitations, and a recommended procedure to be followed in subsequent ELSTAR applications. A companion report, User's Guide to the ELSTAR Photochemical Air Quality Simulation Model, is available to provide user instruction for running the ELSTAR computer program.
