Regional modeling of aerosols and ozone in the arctic : air quality and radiative impacts from local and remote pollution sources
The Arctic is increasingly open to human activity due to rapid warming, associated with decreased sea ice extent. This warming is due, in part, to the effect of short-lived atmospheric pollutants (aerosols, ozone). As a result, Arctic pollutant emissions should increase in the future, and their impa...

The Arctic is increasingly open to human activity due to rapid warming, associated with decreased sea ice extent. This warming is due, in part, to the effect of short-lived atmospheric pollutants (aerosols, ozone). As a result, Arctic pollutant emissions should increase in the future, and their impacts might become significant compared to the now predominant source due to pollution transport from the mid-latitudes. In this thesis, regional simulations of the Arctic troposphere are performed with the WRF-Chem model, combined with new emission estimates for oil and gas extraction and shipping in the Arctic. The model is used to analyze two case studies from recent airborne measurement datasets: POLARCAT-France in 2008, ACCESS in 2012. First, I investigate an aerosol transport event from Europe to the Arctic in spring 2008, in order to improve our understanding of this major source of Arctic pollution.
