    Collection of data sheets and progress reports on TScialo tephra analysis project.

  2. Eruption data for ash-cloud model validation

    04 Apr 2013 | Data Sets/Collections | 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...

  3. Granular Flow Experiments for Validation of Numerical Flow Models

    25 Jun 2016 | Data Sets/Collections | Contributor(s): Amy Webb, Marcus I Bursik

    Many types of geophysical flows such as debris avalanches and pyroclastic flows pose significant danger to both people and property. Understanding granular avalanche behavior and particle interaction during the course of a flow is very important in the development of granular flow models. Since...

    The tarball contains 1) radiosondes over the period of the Eyjafjallajokull eruption from 13 April to 23 May, 2010; 2) webcam videos from Hvolsvollur for 17 April; 3) radar time series from the Keflavik radar, and 4) README file explaining it all.Please do not redistribute without explicit...

  5. GFS 0.5 deg data for Puff from April 17 - 29 2010

    07 Oct 2010 | Data Sets/Collections | Contributor(s): Peter W Webley

    this is the global GFS data, every 6 hrs from April 17 2010 at 00:00. It is ready to be used by the Puff dispersion model, see example lines of codeNote i have defined the location of the wind field, the U, V and Z variables. I specify the model as reanalysis and this allows Puff to read the...
