• Resumen: Greenhouse gases and aerosols from anthropogenic emissions are known to alter the Earth’s radiative balance, thus resulting in climate change. Limited quantitative understanding of the aerosol effects remains the largest source of uncertainty of anthropogenic influence on the radiative balance, thereby causing considerable uncertainty of future climate predictions. Aerosols absorb and scatter solar radiation, which can results in cooling or warming, depending on how aerosol optical properties compare with surface albedo. Optical properties of the main light-absorbing aerosol components inferred from laboratory and field experiments will be addressed in a first part of this presentation dealing with aerosol-radiation interactions. Aerosols also play a key role in cloud formation and for resulting cloud radiative properties as cloud droplets only form on pre-existing particles under atmospheric conditions. Similarly, heterogeneous ice formation on ice nucleating particles is a key process for transformation of super-cooled liquid clouds to glaciated clouds. These aerosol-cloud interactions will be addressed with results from field experiments in Zurich and the high-alpine Jungfraujoch research station at 3480 m a.s.l. in the Swiss alps.
