  1. Eruption data for ash-cloud model validation

    04 Apr 2013 | Contributor(s): Larry Garver Mastin, Costanza Bonadonna, Arnau Folch, peter webley, barbara stunder, Michael Pavolonis

    This is a collection of data, references, and links to data on well-documented eruptions whose observations can be used to validate ash-cloud transport models. Data include, among other things, plume height, duration, erupted volume, satellite observations, numerical wind fields, and grain-size...

  5. Volcanic clouds observed by the A-Train satellite constellation

    12 Mar 2012 | *Data Sets/Collections | Contributor(s): Simon Carn

    A collection of images showing volcanic eruption clouds detected by NASA's A-Train satellite constellation, which includes the Aqua, CALIPSO, CloudSat and Aura satellites. These examples demonstrate the unique ability of the A-Train to provide coincident, multi-spectral, active and passive remote...

  8. Eyjafjallajökull, volcanic clouds and aviation - one year on

    05 Aug 2011 | Workshops | Contributor(s): Simon Carn

    A workshop at the 2011 IUGG General Assembly in Melbourne, Australia, lead by Andrew Tupper (Australian Bureau of Meteorology), Fred Prata (Norwegian Institute for Air Research), and Arnau Folch (Barcelona Supercomputing Center).The Eyjafjallajokull eruption, resulting in ground and air...

  9. Large Scale Experiments on Volcanic Processes (EOS)

    19 Jul 2011 | Publications | Contributor(s): Greg A Valentine

    Some of the least understood and most hazardous geologic processes involve complex multiphase flows, particularly those related to explosive volcanic eruptions. These phenomena inherently involve a wide range of characteristic length and time scales, as well as processes that are coupled across...

  14. Direct sampling of volcanic clouds

    08 Feb 2011 | Presentations | Contributor(s): William I Rose

    Volcanic clouds have only sporadically been directly sampled. Sampling is advantageous to validate remote sensing. Direct sampling was more common in the 1978-1984 period before the hazards to jet aircraft were understood and when piston aircraft sampling was more prevalent. This sampling...
