Mathematical models of acid deposition are complex, requiring significant expenditure of computation time for their implementation. The overall goal of this project was threefold: (1) to prepare and test the SAQM model for use in simulating ozone and acid deposition in California; (2) to improve the computational efficiency of SAQM through improvement of computational algorithms within it and through implementation of parallel computing; and (3) to develop, implement and apply an efficient aerosol module in SAQM. This report contains a description of each of these three tasks. In preparation and testing of SAQM, simulations of ozone air quality in the San Joaquin Valley during the August 3-6, 1990 episode were carried out and are reported. These simulations augment and support those carried out previously by the Air Resources Board and summarized in San Joaquin Valley Air Quality Study: Policy-Relevant Findings, California Air Resources Board, November 1996.
