Model and satellite analysis of transport of Asian anthropogenic pollution to the Arctic: Siberian and Pacific pathways and their meteorological controls
International audience We made comprehensive analyses of long‐range transport episodes of air pollutants from East Asia to the Arctic and associated meteorological conditions. While our main focus was black carbon (BC) as its transport to the Arctic has attracted great attention, carbon monoxide (CO...

In the pathway over Siberia and the Sea of Okhotsk, the pollutants were transported northeastward from China mainly through the Sea of Okhotsk and East Siberia. The low pressures passing from East Siberia to the Sea of Okhotsk played important roles in the transport in the lower troposphere and uplifting to the middle troposphere. In the pathway over the North Pacific, the pollutants were transported eastward from the Asian continent and subsequent northward transport took place over the North Pacific. The poleward transport occurred west of the high pressure that stayed around the Bering Sea.
