Model and Satellite Analysis of Transport of Asian Anthropogenic Pollution to the Arctic: Siberian and Pacific Pathways and Their Meteorological Controls
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) was also diagnosed as...
