Short summary
This study measured particulate matter in the western Canadian Arctic during 2018 as part of the Year of Polar Prediction. It was found that the particles were likely from the ocean, soil, road dust, and combustion. The concentrations of small aerosol particles, which can affect human health, were low, suggesting they had little impact on local air quality. These results can be used to understand future changes in local aerosol particle sources and concentrations.
