1. ASHEE

   14 Aug 2015 | Contributor(s):: Matteo Cerminara, Tomaso Esposti Ongaro

   A fluid-dynamic model is developed to numerically simulate the non-equilibrium dynamics of polydisperse gas-particle mixtures forming volcanic plumes. Starting from the three-dimensional N-phase Eulerian transport equations for a mixture of gases and solid particles, we adopt an asymptotic...

2. Tool for interactive airborne ash detection in a SEVIRI image

   24 Sep 2014 | Contributor(s):: shona mackie

   This is a widget that can be invoked from IDL to display a region of SEVIRI imagery at thermal infrared wavelengths and discriminate airborne volcanic ash within it. Thresholds can be interactively set and applied across the image to create a dynamic ash mask. Thresholds are based on both a...

3. 2nd IUGG-WMO Workshop on Ash Dispersal Forecast and Civil Aviation, Consensual Document

   18 Feb 2014 | Contributor(s):: Costanza Bonadonna, Peter W Webley, Matthew Craig Hort, Arnau Folch, Sue C Loughlin, Herbert Puempel

   An international expert community of volcano observatories, academic scientists, volcanic ash advisory centres and representatives of aviation regulators, engine manufacturers and airlines met in Geneva on 18-20 November 2013 to discuss progress on ash dispersal forecasting and produce a roadmap...
