Size distributions of giant aerosol particles close above sea level

Abstract Vertical profiles of particle concentrations were measured close to the sea surface with a Rotorod impaction sampler. The reliability of the size distributions determined with this instrument has been discussed. Particle concentrations are in good agreement with the results from other experiments. Discrepancies are attributed to differences in windspeed, relative humidity and water temperature. The different sampling techniques may have been of influence as well.
