EGU 2015. session "GMPV6.10 Volcanic ash: local to global"
*****************************************************************************************************
Dear colleagues,
I am writing on behalf of my co-convenors and
myself to invite you to submit a paper to the upcoming EGU session
GMPV6.10: Volcanic ash: local to global.
Volcanic ash particles
are commonly generated during explosive volcanic eruptions. They sit
apart from other eruption products due to their small size (less than 2
mm) and the consequent high surface-to-mass ratio. This peculiarity
carries a plethora of consequences, including the possible long-range
transport as particles in suspension, their high reactivity with the
surrounding environment and the diversity of direct and indirect impacts
as e.g. health hazards because of inhaling, effects on air traffic or
changes of soil fertility. The ash cycle begins with eruptive processes
responsible for its initial formation and injection into the atmosphere.
We stress that several different primary processes can generate
volcanic ash. Advective dispersal and simultaneous chemical-physical
interactions, including aggregation and alteration, further control the
properties of the ash. Finally, remobilization and incorporation into
the environment close the cycle, the ultimate positive or adverse impact
of ash on science, society and the environment depending on the
observation timescale. In this multidisciplinary session we invite
observational, experimental and theoretical contributions on all aspects
of the ash cycle, and especially welcome cross-over and integrated
approaches, broadening our current views of volcanic ash-related
processes.

If you have questions, please feel free to contact me or my co-convenors.
The EGU deadline is 7 January 2015 at 13:00 Central Europe Time.
Looking forward to seeing you in Vienna,
Ulrich Kueppers, Jacopo Taddeucci, Yan Lavallée and Pierre Delmelle
