The experimental measurements were done during two research cruises in the Baltic Sea and during a coastal experiment in Lubiatowo in 1994. The main finding is that aerosol size distribution can be presented as a superposition of a slowly varying background of dust-like particles and a further distribution of sea-spray-sized particles multiplied by amplitude functions reflecting the contribution of marine aerosols. The amplitude is dependent on wind speed, wind direction and fetch. Decrease in aerosol size distribution amplitude with increasing wind speed was found when air fetch over the sea exceeded 400 km. The opposite tendency of increase in aerosol size distribution amplitude was found when air fetch over the water was not longer than 50 km.
