Plume Visualization

The output used to produce these visualizations were created using the Active Tracer High resolution Atmospheric Model (Oberhuber et al., 1998). A myriad of eruptive and atmospheric conditions were tested to understand better the relationship between wind and the stability of explosive eruption columns, The visualizations you see below were created from ATHAM output using MATLAB, the code for which is available at this github repository.  Two isosurfaces are shown in each visualization at .001 g ash/kg air (the outer surface) and 1 g ash/kg air (the inner surface).
