************************************************************************************************
Dear all
We would like to announce an AGU
Fall Meeting session focused on volcanic ash cloud microphysical
processes and particle sedimentation - we look forward to receiving
contributions from both Volcanology and the Atmospheric Sciences.
All the best

Given
the motivation to improve understanding of volcanic cloud microphysics
and ash fallout modeling, we gather research efforts devoted to cloud
evolution over the first week. Contributions that elucidate plume-based
processes and particle conditioning during transport (e.g., convective
ascent, entrainment of tropospheric air, water content, convective
storm analogies, condensation, glaciation, electrification, aggregation,
over-seeding, turbulence, hydration of glass shards, surface conditions
of fine ash, adsorbed gas species, acid and salt coatings), and
sedimentation processes (e.g., aggregation, mammatus development, double
diffusive convection, hydrometeor formation) are strongly encouraged.
Approaches such as direct sampling of volcanic clouds, analysis of
tephra deposits, remote sensing studies, experimental cloud chamber
studies, theoretical modeling, and other topics relevant to accelerated
fallout of small, simple particles with individually small terminal
velocities, are all relevant.
