Short summary
We investigate the atmospheric chemistry that occurs in the plume of Mt. Etna shortly after emission. We measured O3 destruction in the plume. Using simultaneous measurements of SO2 and wind speed, we approximate the rate of this destruction. BrO, expected to be an indicator of ozone-destructive chemistry, is also detected. A computer model is able to approximately reproduce these results and is used to make inferences about the chemistry occurring that cannot be directly observed.
