Joint Session 2 Soil Dust I: Lofting and Transport, Characterization, and Interactions with Clouds and Storms

Monday, 11 January 2016: 1:30 PM-2:30 PM
Room 357 ( New Orleans Ernest N. Morial Convention Center)
Hosts: (Joint between the Eighth Symposium on Aerosol–Cloud–Climate Interactions; and the 18th Conference on Atmospheric Chemistry )
Ottmar Moehler, Institute of Technology, Karlsruhe
Paquita Zuidema, Univ. of Miami/RSMAS, Rsmas/Mpo, Miami, FL and Paola Formenti, Universite Paris Est, Creteil

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.
