The Lance Lab conducts laboratory and field studies to investigate aerosol-cloud-chemistry interactions relevant for climate, visibility and human health. Aerosol particles often cycle many times through clouds during their atmospheric lifetime, which can have substantial impact on their chemical and physical properties. Organic compounds are of particular interest, as oxidation reactions of volatile organic compounds from both anthropogenic and biogenic sources continue to be a major, but poorly understood, driver for aerosol mass loadings and regional haze in an era of greater worldwide controls on sulfur emissions.
