The global marine organic aerosol budget is investigated by a 3-dimensional chemistry-transport model considering recently
proposed parameterisations of the primary marine organic aerosol (POA) and secondary organic aerosol (SOA) formation
from the oxidation of marine volatile organic compounds. MODIS and SeaWiFS satellite data of Chlorophyll-a and ECMWF
solar incoming radiation, wind speed, and temperature are driving the oceanic emissions in the model. Based on the adopted
parameterisations, the SOA and the submicron POA marine sources are evaluated at about 5 Tg yr-1 (~1.5 Tg C yr-1) and 7 to
8 Tg yr-1 (~4 Tg C yr-1), respectively. The computed marine SOA originates from the dimethylsulfide oxidation (~78%), the
potentially formed dialkyl amine salts (~21%), and marine hydrocarbon oxidation (~0.1%). Comparison of calculations with
observations indicates an additional marine source of soluble organic carbon that could be partially encountered by marine POA
