Due to the adverse effect of atmospheric aerosols on public health and their ability to affect climate, extensive research has been undertaken in recent decades to understand their sources and sinks, as well as to study their physical and chemical properties. Atmospheric aerosols are important players in the Earth’s radiative budget, affecting incoming and outgoing solar radiation through absorption and scattering by direct and indirect means. While the cooling properties of pure inorganic aerosols are relatively well understood, the impact of organic aerosols on the radiative budget is unclear. Additionally, organic aerosols are transformed through chemical reactions during atmospheric transport. …

Summer Research
A method for analyzing the three-dimensional surface roughness on the basal facets of polar ice crystals is presented. A functional form of backscattered electron intensity as a function of ice facet orientation is adapted for the use of the basal facet. Using the Gauss-Newton inversion within a Bayesian framework a three dimensional representation of rough surfaces are retrieved at roughly micrometer resolution. Following the development of new statistical measures allow for higher statistical confidence and the connection to a scaling growth mechanism for crystal development. In a collection of results from temperatures ranging from -29 degrees celsius to -35 degrees …
