A six year satellite-based assessment of the regional variations in aerosol indirect effects (2009)
T. A. Jones, S. A. Christopher, J. Quaas
Aerosols act as cloud condensation nuclei (CCN) for cloud water droplets, and changes in aerosol concentrations have significant microphysical impacts on the corresponding cloud properties. Moderate...

Effects of absorbing aerosols in cloudy skies: a satellite study over the Atlantic Ocean (2009)
K. Peters, J. Quaas, N. Bellouin
Aerosol effects, direct as well as indirect, constitute one of the biggest sources of uncertainty when it comes to quantifying human forcing of climate change. Understanding these will thus increase...
A six year satellite-based assessment of the regional variations in aerosol indirect effects (2008)

Lohmann, U., Quaas, J., Kinne, S., Feichter, J.
Assessments of the influence of aerosol emissions from human activities on the radiation budget, in particular via the modification of cloud properties, have been a challenge. In light of the...
