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...

OMIplot is a software package that can be used to ingest, visualize and analyze sulfur dioxide (SO2) data from the Ozone Monitoring Instrument (OMI) aboard NASA's Aura satellite. The OMI SO2 measurements can be used to track drifting volcanic eruption clouds and study volcanic degassing. OMI...
