| Zusammenfassung |
| The effects of atmospheric aerosol on climate forcing may be very
substantial but are quantified poorly at present; in particular, the
effects of aerosols on cloud radiative properties, or the "indirect
effects" are credited with the greatest range of uncertainty amongst
the known causes of radiative forcing. This manuscript explores the
effects that the composition and properties of atmospheric aerosol
can have on the activation of droplets in warm clouds, so
potentially influencing the magnitude of the indirect effect. The
effects of size, composition, mixing state and various derived
properties are assessed and a range of these properties provided by
atmospheric measurements in a variety of locations is briefly
reviewed. The suitability of a range of process-level descriptions
to capture these aerosol effects is investigated by assessment of
their sensitivities to uncertainties in aerosol properties and by
their performance in closure studies. The treatment of these effects
within global models is reviewed and suggestions for future
investigations are made. |
