CliSAP successfully finished in 2018. Climate research continues in the Cluster of Excellence "CLICCS".

Volcanic Ash as an Active Agent in the Earth system

12.09.2016 - 13.09.2016

The primary topics of the workshop are the state-of-the-art experimental and modelling techniques to study volcanic ash surface with respect to physical, chemical and mineralogical properties; ash generation and volcanic processing; atmospheric transport and processing and environmental and climatic impacts.

Venue: B53 Building, Bundesstr. 53, Universität Hamburg, 20146 Hamburg, Germany
Organizers: Ali Hoshyaripour, Matthias Hort, Jens Hartmann

Summary:
Volcanic ash emission, dispersion and deposition can lead to widespread impacts upon different components of the Earth system (e.g. atmosphere, hydrosphere and biosphere), which are directly linked to the physical, chemical and mineralogical properties of the ash. In particular, ash surface characteristics play a key role in its interaction with the surrounding environments. To investigate the volcanic and atmospheric processes that shape these properties, numerical models and experimental techniques have been developed and deployed by different research groups. The proposed workshop aims to integrate the developments in this field and increase collaboration between these groups.

Topics:
The primary topics of the workshop are the state-of-the-art experimental and modeling techniques to study volcanic ash surface with respect to:
1. Physical, chemical and mineralogical characteristics
2. Generation and volcanic processing
3. Atmospheric transport and processing
4. Environmental and climatic impacts

The main objectives of the workshop are to address:
1. State-of-the-art and future directions
2. Premier knowledge gaps and the potential theoretical and experimental solutions
3. Essential considerations to foster model-experiment coupling in volcanic ash research

Structure of lecture sessions: Session will begin with two lectures from the participating experts (45 minutes each), followed by round-table discussions (1 hour). A 15 minutes break is considered within each session.

Structure of poster sessions: Each participant should present a poster. The session will begin with 10 short talks (three minutes madness) by each presenting author followed by a 45 minutes classic poster session for detailed discussions on each poster for interested participants.

Targeted Audiences:
The workshop targets the PhD students, postdocs and experienced scientists working in various research disciplines but on topics directly related to volcanic ash.

Application procedure:
Please submit an abstract (max. 500 words) and a CV (max 3 pages) until 15.07.2016 to the following email address: gholamali.hoshyaripourdummy@uni-hamburgdummy2.de. Because of limited number of places (20 places), only the applications submitted before the above deadline will receive full consideration.
There is no registration fee for the workshop. The host institute will NOT cover the travel costs of the participants.
