Abstract In remote atmospheric locations, such as in the Arctic, the size distribution and climate impacts of particles is sensitive to the balance of long-range transport, local primary aerosol sources, local aerosol precursor-vapor emissions, the availability of gaseous bases, and wet scavenging/chemistry. Due to the distance from major mid-latitude sources, the size distributions and aerosol-climate impacts are quite sensitive to relatively small uncertainties in many of these processes. In this talk, I will highlight recent measurements and modelling work describing seasonal and day-to-day variability in the Arctic, and show how this work has provided insight into several the processes described above.
