Project Description

The primary goals of this proposal are to (1) develop unique high-time-resolution, millennial-scale records of biomass burning, dust, volcanic, industrial pollution, and sea salt aerosols for two ice core sites inside the Arctic polar dome and (2) use new and leveraged general circulation models (GCM) and other modeling to interepret these and similar ice core records from outside the polar dome to better understand source regions and transport pathways of aerosols to different regions of the Arctic and their climatic and environmental impacts.
