Abstract
The aging processes of two representative natural aerosol, sea-salt and mineral aerosol, are investigated by using a box model equipped with a thermodynamic module (SCAPE). The model is shown to successfully describe the aging processes between the gas-phase anthropogenic pollutants (SO
2, NO
x
, and NH
3) and primary aerosol particles, including self-neutralization process/chlorine depletion in the sea-salt aerosol; formation/dissipation of carbonate and bicarbonate ions in the mineral aerosol; irreversible dynamic deposition of SO
2 and H
2SO
4; and reversible thermodynamic distribution of inorganic volatile species. It is found that SO
2 and H
2SO
4 tend to deposit onto the mode with the largest surface area, and that ammonia deposition is controlled by preceding SO
2/H
2SO
4 deposition. During the SO
2/H
2SO
4 deposition, chloride and carbonate are continuously released from the sea-salt and mineral dust particles, respectively. The findings by the model predictions are consistent with field and observational studies.
