Fig. 5: Conceptual overview of anthropogenic-dominated versus natural-dominated Arctic OAs.
From: Equal abundance of summertime natural and wintertime anthropogenic Arctic organic aerosols
A conceptual image of anthropogenic-dominated and natural-dominated emissions that drive the OA mass in the Arctic in winter and summer, respectively. The most important geographical source regions are indicated by the arrows. Bars show the entire-dataset average contributions of nearly equally contributing summed anthropogenic-dominated (blue) and summed natural-dominated (green) organic components.
