The Arctic is a remote, desolate region, seemingly far away from human influence. However, during the 1970s, large amounts of anthropogenically-emitted particles were detected in the Arctic atmosphere, inferring that long-range transport of pollution could harm even the most pristine parts of the globe.

These pollutants can drastically affect the Arctic climate, either directly by scattering or absorbing sunlight, or indirectly by changing microphysical cloud properties, snow albedo, etc. My research addresses this process, by using climate models to trace aerosols as they are emitted from mid-latitudes, transported to the Arctic, and interact with radiation and clouds
