AM7Special session: Volcanic ash event 2010
Airborne volcanic ash represents a major hazard to aviation, and several National Met Services operate Volcanic Ash Advisory Services (VAAC) to advise aviation on hazard areas in the event of eruptions. The eruption of the Eyjafjallajokull volcano in Iceland in April 2010 caused unprecedented disruption to aviation when the plume was carried over much of NW Europe. This raised many questions over the levels of confidence and uncertainty in the VAAC forecasts and in the potential impact of ash concentrations on aviation.
Papers are invited on any aspect of volcanic ash monitoring and prediction including:
- quantification and vertical profiling of volcanic ash emissions - the source term
- dispersion modelling including ensemble modelling and uncertainty estimation
- ash measurement and monitoring from remote sensing, airborne and in-situ observations
- hazard estimation and the impact of ash on aircraft and engines
- safety-critical decision-making in the face of significant uncertainty.
