Sources of carbonaceous aerosols and deposited black carbon in the Arctic in winter-spring: implications for radiative forcing
We use a global chemical transport model (GEOS-Chem CTM) to interpret observations of black carbon (BC) and organic aerosol (OA) from the NASA ARCTAS aircraft campaign over the North American Arctic in April 2008, as well as longer-term records in surface air and in snow (2007–2009). BC emission inv...
