IDL plotting code from NETCDF files generated by Matlab - Generating Probabilities Exceeding Threshold Results
27 May 2016 | Contributor(s):: Peter W Webley
This is the IDL pro files needed to plot the NETCDF outputs from Reza's Matlab code. There is a WORD file that explains each IDL pro file. You will also need the associated PNG files.

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...

Size of volcanic ash
08 Feb 2011 | | Contributor(s):: William I Rose
Size of ash particles is discussed--ash, lapilli, fine and very fine ash, phi sizes, lognormal distributions and bimodal ones. Patterns of fallout and grain size distributions.
Origin of volcanic ash: Mechanisms for formation
Mechanisms for the formation of volcanic ash are reviewed and discussed, including explosive vesiculation, phreatomagmatic explosions and milling/comminution.
