Atmospheric concentration of black carbon in the western Arctic

Black carbon (BC) influences the Arctic climate by altering the radiation budget. Measurements of atmospheric BC concentration are rare in the Arctic. Furthermore, literature providing information about the current BC concentration or about its evolution refers almost exclusively to ground measureme...
