Atmospheric aerosols and clouds play important roles in determining the Earth’s climate. Trace gases and aerosols, constitute only a tiny fraction of the atmospheric mass, however they interfere with the solar radiative transfer through the atmosphere. Along with molecular scattering and absorption from gases, aerosol particles and clouds determine in part what fraction of solar radiation reaches the Earth’s surface and what fraction of it returns to space. Aerosol particles are especially complex. Particles can exert both a direct effect by reflecting and absorbing solar radiation. They also promote an indirect effect by influencing cloud properties and lifetimes. Water uptake by particles is responsible for haze formation, cloud formation, and can affect the amount of water vapor in the atmosphere, thus it is a key indirect effect. Overall, the uncertainty in aerosol radiative forcing is considerably larger than that due to greenhouse gases (IPCC 1996, 2007). This limits our scientific ability to predict future surface temperature changes and to unambiguously detect a greenhouse warming signal. Organic aerosol components arise from a combination of anthropogenic and biogenic sources. These include but are not limited to: biomass combustion, vehicle emissions, meat cooking, secondary reactions, and emissions from plants and animals. The components of aerosol may either by emitted to the atmosphere as fine particulate matter or as gases.
Dr. Mazzoleni's primary research interests are to identify organic aerosol constituents from a variety of atmospheric environments. Her research group uses advanced mass spectrometry (MS) techniques to identify organic molecules from atmospheric complex mixtures. Her group has participated in a number of ambient and laboratory studies and is complying a large database of molecular observations to unravel the complex nature of ambient aerosol. Currently, Dr. Mazzoleni is the lead investigator of collaborative research carried out at the Pico Mountain Observatory in the Azores (PT) to understand the chemical, physical, and radiative properties of North Atlantic free tropospheric aerosol sponsored by the National Science Foundation. Dr. Mazzoleni is also co-investigator with Dr. Raymond Shaw for the development of a turbulent cloud chamber also sponsored by the National Science Foundation. The cloud chamber will facilitate novel studies of aqueous aerosol and cloud processing of ambient water soluble gases.
