- •
We tested the sensitivity of eruption plume height and atmospheric mass loading to source conditions and parameters.
- •
Vent radius and initial speed have a more profound effect on model outputs than does grain size distribution.
- •
Rise height and mass loading are sensitive to entrainment parameters, but also wind speed.
- •
Efforts to better characterize entrainment parameters are important.
- •
Accurate, local meteorological data should be collected.
