Joint Session 4 Soil Dust I: Lofting, Transport, Characterization, and Interactions with Clouds and Climate

Monday, 8 January 2018: 8:45 AM-9:45 AM
Room 9AB (ACC) (Austin, Texas)
Hosts: (Joint between the 10th Symposium on Aerosol-Cloud-Climate Interactions; and the 20th Conference on Atmospheric Chemistry )
Ottmar Möhler, Karlsruhe Institute of Technology, Institute of Meteorology and Climate Research, Karlsruhe and Naruki Hiranuma, West Texas A&M Univ., Department of Life, Earth and Environmental Sciences, Canyon, TX

Soil dust from a variety of sources contributes a major fraction to the atmospheric aerosol and has strong impacts on the environment, the weather systems, and the global climate. The goal of this session is to bring together scientists from different disciplines working on the emission, atmospheric transport, transformation, physical, and chemical characterization, as well as cloud, weather, and climate impacts of soil dust from deserts, semi-arid regions, or agricultural areas. Of particular interest are questions about the speciation and atmospheric impact of different mineral, organic, and biological components in the soil dust of different origin. We invite and welcome laboratory, field, and modeling contributions from the general areas of (1) 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, weather, and climate impact, including optical properties and cloud microphysics like CCN activation and heterogeneous ice nucleation.
