Some Characteristics of Background Aerosols Over the Pacific Ocean

Abstract

Measurements of the total aerosol concentration and the size distribution of large particles have been performed over the North and South Pacific ocean from November 18, 1971 to March 10, 1972. It was found that the concentration was about 300 cm^-3 on an average over the South-Pacific and 450cm^-3 over the North Pacific. Both the concentration and the size distribution of large particles depended on the wind force and showed a pronounced peak around 0.4×10^-4cm in radius.
