Abstract

Atmospheric processes such as surface absorption and reflectance are dependent on aerosol composition and aging processes. Our studies examined four atmospheric processes. First, mole ratio effects on deliquescence of mixed binary particles were analyzed. Experimental mole ratio results match established atmospheric model calculations and show that binary component concentrations affect the deliquescence relative humidity (DRH). Second, hydrogen chloride (HCl) gas formation as a function of humidity was investigated. HCl production influences pH of aerosols and was found to be independent of humidity conditions. Third, particles collected in Northeast Arkansas were found to be indicative of urban or rural point sources. Urban particles contained pollutants (sulfates, fluorides, phosphates) while rural particles showed high agriculture activities (bromine, chlorine). Fourth, the reaction between dimethyl sulfoxide (DMSO) and carboxylic acids was explored. DMSO was not found to react with carboxylic acids.
