The 'indirect'radiative cooling of climate due to the role of anthropogenic aerosols in cloud
droplet formation processes (which affect cloud albedo) is potentially large, up to− 1.5 W m …

Atmospheric acidity is increasingly determined by carbon dioxide and organic acids,–.
Among the latter, formic acid facilitates the nucleation of cloud droplets and contributes to …

A list of authors and their affiliations appears at the end of the paper New-particle formation
is a major contributor to urban smog,, but how it occurs in cities is often puzzling. If the …

SEVERAL workers have investigated the numbers and sizes of droplets expelled during
expiratory manoeuvres such as coughing or sneezing. When droplets are recovered by …

ANTHROPOGENIC sulphate aerosols are believed to affect the radiation budget of the Earth
in two ways. Through the direct effect they scatter solar radiation back to space, producing a …

Particles lofted into the atmosphere by desert dust storms can disperse widely and affect
climate directly through aerosol scattering and absorption. They can also affect it indirectly …

About half of present-day cloud condensation nuclei originate from atmospheric nucleation,
frequently appearing as a burst of new particles near midday. Atmospheric observations …

Dry fogs appear in the atmosphere when large volcanic eruptions inject massive quantities
of fine silicate ash and aerosol-forming sulphur gases into the troposphere and stratosphere …

Marine aerosol contributes significantly to the global aerosol load and consequently has an
important impact on both the Earth's albedo and climate. So far, much of the focus on marine …

Ground-based measurements strongly support the hypothesis that pollutant materials of
anthropogenic origin are being trans ported over long distances in the mid-troposphere and …
