TRANSPORTATION SYSTEMS AND REGIONAL AIR QUALITY--PHOTOCHEMICAL MODELING OF SACRAMENTO, CALIFORNIA REGION

In cooperation with the California Air Resources Board and the Sacramento Regional Area Planning Commission, regional modeling was performed simulating a high ozone day in Sacramento, California. The study area was selected to include populated sections of Sacramento. An air pollution emission inventory was taken for the study area. Field gathering of meteorologic and aerometric data was done in the summer of 1976. Verification of two models, the SAI 15-step chemistry and the SMOG models was attempted. A verification was not effected with the SAI model, but the SMOG model seemed to verify. Problems involved with the use of each model are discussed as are the unique properties of the models. The SMOG model results depended significantly more on initial conditions than on emission levels. (FHWA)
