Secondary organic aerosol formation and transport. Pandis, S., N., Harley, R., A., Cass, G., R., & Seinfeld, J., H. Atmos Environ Pt A-Gen Top, 26:2269-2282, 1992. abstract bibtex A Lagrangian trajectory model simulating the
formation, transport and deposition of secondary organic aerosol is
developed and applied to the Los Angeles area, for the air
pollution episode of 27-28 August 1987. The predicted secondary
organic aerosol on 28 August 1987 represents 15-22% of the
measured particulate organic carbon at inland locations in the base
case simulations, and 5-8% of that at coastal locations. A
maximum secondary organic aerosol concentration of 6.8-mu-g m-3 is
predicted for Claremont, CA, during this episode. On a daily
average basis at Claremont about 46% of this secondary organic
aerosol is predicted to be a result of the oxidation of non-toluene
aromatics (xylenes, alkylbenzenes, etc.), 19% from toluene, 16%
from biogenic hydrocarbons (alpha-pinene, beta-pinene, etc.), 15%
from alkanes and 4% from alkenes. The major uncertainties in
predicting secondary organic aerosol concentrations are the
reactive organic gas emissions, the aerosol yields and the
partitioning of the condensable gases between the two phases.
Doubling the reactive organic gas (ROG) emissions results in an
increase of the secondary organic aerosol predicted at Claremont by
a factor of 2.3. Predicted secondary organic aerosol levels are
less sensitive to changes in secondary organic aerosol deposition
and NOx emissions than to ROG emissions.
