Ozone depletion in tropospheric volcanic plumes
Listed in National Center for Atmospheric Research
We measured ozone Oâ concentrations in the atmospheric plumes of the volcanoes St.
Description
Augustine (1976), Mt. Etna (2004, 2009) and Eyjafjallajökull (2010) and found Oâ to be strongly depleted compared to the background at each volcano.
At Mt. Etna Oâ was depleted within tens of seconds from the crater, the age of the St. Augustine plumes was on the order of hours, whereas the Oâ destruction in the plume of Eyjafjallajökull was maintained in 1-9 day old plumes.

The most likely cause for this Oâ destruction are catalytic bromine reactions as suggested by a model that manages to reproduce the very early destruction of Oâ but also shows that Oâ destruction is ongoing for several days. Given the observed rapid and sustained destruction of Oâ, heterogeneous loss of Oâ on ash is unlikely to be important.
