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...

D-Compress computes the gas and melt volatile composition of five element sets in magmatic systems (O–H, S–O–H, C–S–O–H, C–S–O–H–Fe, and C–O–H). It has been calibrated so as to simulate the volatiles coexisting with three...
Volcanic clouds observed by the A-Train satellite constellation
12 Mar 2012 | 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...
