Abstract

Three basic modules of gas-phase photochemical reactions involved in the formation of secondary aerosol are developed for modeling the concentration variation of precursors of aerosol, including ketone (RCO_x), aldehyde (ALD), peroxyacetylnitrate (PAN), NO₂, and SO₂, followed by numerical solution for each of the modules. Reasonable trends of concentration variation of the precursors can be obtained from the proposed modules.
