Effects of Aerosols on the Radiative Properties of Clouds

摘要: The influence of anthropogenic aerosols, in the form ship exhaust effluent, on microphysics and radiative properties marine stratocumulus is studied using data gathered from U.K. Met. Office C-130 University Washington C-131A aircraft during Monterey Area Ship Track (MAST) experiment 1994. During period MAST, clouds were 11 flights a wide range levels background pollution was observed. impact aerosol emitted ships found to be very dependent cloud microphysical conditions. In continental influence, susceptibility further emissions low, with correspondingly weak radiation signature tracks. clean clouds, changes droplet concentration factor 2, reductions size up 50%, measured. These had significant impacts forcing. Furthermore, as result being reduced, some cases drizzle suppressed resulting an increase liquid water path polluted track environment. this combined change radius forcing by 4.
