Lay summary
Summary and background:Black carbon (BC) aerosols influence the Earth's radiative budget directly by absorbing incoming solar radiation and indirectly by acting as cloud condensation nuclei (CCN) and ice nuclei (IN), and thereby changing microphysical and radiative properties of the clouds. The influence of BC on warm, mixed-phase and cold cloud indirect effects is highly uncertain due to an insufficient characterization of BC-sources, insufficient information on the physico-chemical properties of ambient BC particles, and an inadequate understanding and hence description of the aerosol-cloud interactions and microphysical processes applied in climate models. We propose to perform field and laboratory studies of the chemical composition and mixing state of BC particles and their ability to act as cloud condensation and ice nuclei. The results will help to understand the dependence of water and ice nucleating behavior of BC particles on their chemical composition and mixing state, and to identify distinct BC sources. Aims and relevance:The understanding and investigation of climate change and related atmospheric processes is a highly topical research field and subject of academic and public interest. The recent 2007 report of the IPCC (Intergovernmental Panel of Climate Change) stressed the need to improve our understanding of the aerosol radiative forcing component for constraining it's climate impact more accurately. The lack of understanding of the aerosol effects on climate is mainly due to the lack of knowledge of aerosol-cloud interactions. Herein, the proposed laboratory and field experiments will provide new data to improve aerosol-cloud interactions in climate and process-related models and to reduce the uncertainties of the anthropogenic influence on climate via the direct and indirect effect aerosol effects. Moreover, the new measurement approach we propose herein for source apportionment of BC particles, i.e. identify and quantify distinct BC sources, is of interest for local climate change estimates and questions related to air pollution and public health. This is due to the fact that our field measurements focus on particles emitted locally (in Switzerland) and transported on a regional scale. However, the role of BC emissions from residential heating is far more important in other region of the world.

Abstract

Black carbon (BC) aerosols influence the Earth’s radiative budget directly by absorbing incoming solar radiation and indirectly by acting as cloud condensation nuclei (CCN) and ice nuclei (IN), and thereby changing microphysical and radiative properties of the clouds. The influence of BC on warm, mixed-phase and cold cloud indirect effects is highly uncertain due to an insufficient characterization of BC-sources, insufficient information on the physico-chemical properties of ambient BC particles, and an inadequate understanding and hence description of the aerosol-cloud interactions and microphysical processes applied in climate models.Aerosol-cloud interactions are governed by the ability of a particle to act as CCN and IN which depends on various parameters. This includes particle size, shape, structure, mixing state, its chemical composition, and the supersaturation in the cloud. In the context of BC, the knowledge of the mixing state and the chemical composition is of major importance. Fresh BC aerosols age during their residence time in the atmosphere by developing a coating of secondary species and become internally mixed with other chemical components. The properties of the coating material determine whether the particle is activated to a cloud droplet or an ice crystal. However, detailed studies of the chemical composition and the mixing state in connection with CCN- and IN-activity of BC particles are still scarce and - to our knowledge - simultaneous in situ measurements of these physico-chemical properties have not been performed yet.We propose to perform field and laboratory studies of the chemical composition and mixing state of BC particles and their ability to act as cloud condensation and ice nuclei. In the framework of two field campaigns, CCN-activity, IN-activity, and the chemical composition of atmospheric aerosols will be measured simultaneously and in situ, deploying an exclusive set of instrumentation especially suitable for the chemical characterization of BC particles and their mixing state. The instrumental approach involves the utilization of two different mass spectrometers, whose measurement features complement each other, to characterize ambient BC in large detail. This includes a new variant of an aerosol mass spectrometer capable to quantify BC mass and coating material. CCN- activity will be measured using a Cloud Condensation Nuclei Counter, and IN-activity using the Portable Ice Nucleation Chamber PINC developed at ETH Zurich. The field measurements will be accompanied by laboratory experiments investigating coated BC particles.The results will help to understand the dependence of water and ice nucleating behavior of BC particles on their chemical composition and mixing state, and to identify distinct BC sources. The proposed laboratory and field experiments will provide new data to improve aerosol-cloud interactions in climate and process-related models and to reduce the uncertainties of the anthropogenic influence on climate via the direct and indirect effect aerosol effects.
