WRF-Chem numerical analysis of YAK-AEROSIB aircraft data with BC emissions from Russian oil/gas flarings evaluated by satellite data
International audience Arctic air pollution originates mainly from long-range transport of short-lived climate forcers (SLCFs), including black carbon(BC), ozone, and their precursors, from mid-latitudes and, also from important local anthropogenic emissions from activities suchas resource extractio...
