It is universally understood that climate warming is greater and more impactful over the Arctic. Warming is exacerbated in the Arctic by phenomena such as the premature melting of ice and snow that is induced by the deposition of dust and smoke (aerosol) particles on these surfaces. It is accordingly of critical importance that the properties of Arctic aerosols be measured and accounted for in climate change models. The key research goals focus on understanding the dynamics of remotely sensed Arctic aerosols. To achieve this goal, the team will investigate (i) aerosol events observed over the last 18 years at the high-Arctic PEARL observatory (Polar Environment Atmospheric Research Lab) at Eureka, Nunavut and (ii) a new set of more recent observations at CHARS (Canadian High-Arctic Research Site) at Cambridge Bay, Nunavut. This research will inform future satellite missions to observe aerosols by using measurement-driven aerosol simulation models.
