Dust from both desert and more vegetated areas contributes a major fraction of the atmospheric aerosol with a variety of sources, compositions and impacts. The goal of this session is to bring together scientist from different disciplines working on the characterisation, emission, atmospheric transport, chemical transformation and impact of dust from desert, vegetated or agricultural areas, not only including mineral but also organic and other constituents. We invite and welcome contributions from the general areas (1) speciation and characterisation of the mineralogy, organic content and other constituents of dust sampled from source regions or directly from the atmosphere, (2) emission fluxes, transport and chemical transformation of dust in the atmosphere, and (3) cloud and climate impact of atmospheric dust, including optical properties and cloud microphysics like CCN activation and heterogeneous ice nucleation.
