Light extinction by particles is strongly dependent on chemical composition, particle size, and water uptake. Relative humidity affects extinction by causing changes in refractive index and particle size due to hygroscopic growth. The ability of particles to take up water depends on its composition and structure. Organic compounds and inorganic salts are often found to be internally mixed within the same aerosol particle. There is currently a great deal of interest in aqueous particles with an insoluble organic coating. The impact of organic films on particle water uptake is uncertain. The Tolbert group uses cavity ring-down aerosol extinction spectroscopy (CRD-AES) to investigate aerosol optical properties. My research in the Tolbert group uses CRD-AES to study the aerosol optical properties of sodium chloride and/or ammonium sulfate inorganic cores coated by insoluble organics. |
