A global three-dimensional chemical transport model (CTM) is used to model the yearly cycle of sea salt.<lb>Sea salt particles are produced by wind acting on the sea surface, and they are removed by wet and dry deposition.<lb>In this study, forecast meteorological data are taken from the ECMWF. The modeled concentrations are compared<lb>to measured concentrations at sea level, and both absolute values and monthly variations compare well with<lb>measurements. Radiation calculations have been performed using the same meteorological input data as the<lb>CTM calculations. The global, yearly average burden of sea salt is found to be 12 mg m22. This is within the<lb>range of earlier estimates that vary between 11 and 22 mg m22. The radiative impact of sea salt is calculated<lb>to be 21.1 W m22. The total, yearly flux of sea salt is estimated to be 6500 Tg yr21.
