| Abstract: | Smog aerosol can be related to sources, atmospheric transport, and particle growth through a Lagrangian model. Sample calculations indicate that the midday Pasadena aerosol is dominated by material produced in the atmosphere, and that the afternoon drop in aerosol mass is due to the advection of cleaner air. Numerical experiments suggest that control of primary particulate emissions without corresponding control of reactive gases would not substantially improve visibility. |
