Abstract: The relationships between acidity and the principal chemical constituents of precipitation (including sulfate, nitrate, ammonium, calcium, magnesium, sodium, and chloride) were investigated using a new archive of daily ...

Abstract: Cloud condensation nucleus (CCN) spectral data are presented for the Arctic in spring, which considerably augment the existing meager CCN database for the Arctic. Concurrent measurements of sulfate mass suggest that men ...

Abstract: Airborne measurements of aerosol light-scattering efficiencies are presented for a portion of the northeast Atlantic seaboard of the United State during July 1993. The measurements suggest a value for the sulfate ...

Abstract: Polycyclic aromatic hydrocarbons (PAHs) have been sampled in marine stratiform clouds to identify the contribution of anthropogenic combustion emissions in activation of aerosol to cloud droplets. The Monterey Area Ship ...

Abstract: The influence of anthropogenic aerosols, in the form of ship exhaust effluent, on the microphysics and radiative properties of marine stratocumulus is studied using data gathered from the U.K. Met. Office C-130 and the ...

Abstract: Airborne measurements from the Meteorological Research Flight?s Hercules C-130 and the University of Washington?s Convair C-131A during the Monterey Area Ship Track field project are used to evaluate Twomey?s analytic ...

Abstract: Although drizzle was a relatively infrequent occurrence during the Monterey Area Ship Track study, diverse measurements from several sources produced data signals consistent with a reduction in drizzle drops in stratus ...

Abstract: A case study of the effects of ship emissions on the microphysical, radiative, and chemical properties of polluted marine boundary layer clouds is presented. Two ship tracks are discussed in detail. In situ measurements ...

Abstract: The effects of anthropogenic particulate emissions from ships on the radiative, microphysical, and chemical properties of moderately polluted marine stratiform clouds are examined. A case study of two ships in the same air ...

Abstract: Emissions of particles, gases, heat, and water vapor from ships are discussed with respect to their potential for changing the microstructure of marine stratiform clouds and producing the phenomenon known as ?ship tracks.? ...
