Joint Session 5 Soil Dust Part I: Lofting, Transport, Characterization, and Interactions with Clouds and Climate

Wednesday, 25 January 2017: 8:30 AM-10:00 AM
4C-4 (Washington State Convention Center )
Hosts: (Joint between the 19th Conference on Atmospheric Chemistry; and the Ninth Symposium on Aerosol–Cloud–Climate Interactions )
Cochairs:
Ottmar Moehler, Institute of Technology, Karlsruhe and Sonia M. Kreidenweis, Colorado State Univ., Atmospheric Science Department, Fort Collins, CO

Dust from both deserts and more vegetated areas contributes a major fraction of the atmospheric aerosol and has a variety of sources, compositions and impacts. The goal of this session is to bring together scientists from different disciplines working on the characterisation, emission, atmospheric transport, chemical transformation and impact of dust from desert, vegetated or agricultural areas. 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 impacts of atmospheric dust, including optical properties, CCN activation, and heterogeneous ice nucleation behaviors.
