Field measurements of large marine aerosols (radius, r >60 pm)were performed at an elevation of 6m above the mean sea surface under high wind velocities (U>9m/s). Sizes and concentrations of large droplets were measured via an optical technique. From these measurements, aerosol size spectra have been constructed and are used to complete the marine aerosol spectrum. In the meantime, sea-salt concentrations were simultaneously measured and are incorporated with spray data to ionfirm the shape of the entire aerosol spectrum. In doing so, the Gathman aerosol model , which predicts the effect of the entire aerosol spectrum on atmospheric propagation, is verified. |
