Abstract

Abstract The role of free radicals, organic compounds and transition metals on in-cloud sulfate production is studied using a flow through reactor model approach. The sensitivity of the model predictions to initial conditions and model parameters are evaluated by calculation of local elementary sensitivity coefficients and by calculation of the Green's function. The presence of organic species is shown to affect sulfate production by changing the free radical concentrations and by the formation of higher peroxides, aldehydes and organic acids. Soluble iron, under daytime conditions, increases sulfate production by increasing the OH concentration.
