Potential source regions of biogenic aerosol number concentration apportioning at King George Island, Antarctic Peninsula
International audience Nowadays it is well accepted that background aerosols in the boundary layer over remote oceans are of marine origin and not aged continental. Particularly in the Atlantic sector of the Southern Ocean at least four main important regions exhibit significant ocean primary produc...
