N2 - A number of investigators have observed substantial amounts of coarse fraction (D>1 μm) non-sea-salt or excess sulfate (XSO4) to prevail in marine boundary layer (MBL) aerosol. Its dry deposition velocity may be 1 cm s-1 or more with low uncertainty relative to the dry deposition velocity of fine-fraction XSO4. Estimates of total sulfur dry deposition using MBL ambient air data over the western North Atlantic Ocean are presented. It is shown, at distances of hundreds to 1000 km downward from sulfur source regions, that sulfur dry removal from the western North Atlantic MBL is dominated by the dry deposition of XSO4 rather than that of SO2. -Authors
