-- Select Graphics --

Simulation Length: Forecast ash particle movement through this length of time		hrs
Save Interval: Save an ash file and create graphics every n hours over the simulation length		hrs
Eruption Duration: Continuously emit particles from the start time through this length of time. The default value uses the total 'Simulation Length' value. A value of zero emits all particles in the first timestep and the cloud 'detaches' from the source as it travels.		hrs
Plume Height: Set the maximum ash height for the eruption. The default value uses the rough maximum height of the initial wind model data.		ft
Plume Base: Set the minimum ash height of the eruption. This defaults to zero since most wind model data do not include topography.		ft
Horizontal Diffusivity: Set the horizontal spreading parameter. Larger values result in higher dispersion of the particles over time.		m2/s
No. Particles: Total number of particles to emit over the 'Eruption Duration' period.
