Cross-polar transport and scavenging of Siberian aerosols containing black carbon during the 2012 ACCESS summer campaign
International audience During the ACCESS airborne campaign in July 2012, extensive boreal forest fires resulted in significant aerosol transport to the Arctic. A 10 day episode combining intense biomass burning over Siberia and low-pressure systems over the Arctic Ocean resulted in efficient transpo...
