Volcanic eruptions are known to be a major source of SO2 and some reactive halogen species notably HCl and HF. Recent studies have however observed the presence of large amounts of BrO with tight correlation to SO2 in a volcanic plume by ground‐based spectroscopic measurements. In this work, upper limits of BrO columns have been estimated for a number of volcanic eruptions observed in measurements made by two satellite instruments ‐ the Global Ozone Monitoring Experiment (GOME), and the new… 

Systematic investigation of bromine monoxide in volcanic plumes from space by using the GOME-2 instrument

Abstract. During recent years, volcanic emissions turned out to be a natural source of bromine compounds in the atmosphere. While the initial formation process of bromine monoxide (BrO) has been

Detection of bromine monoxide in a volcanic plume

The estimate of BrO emission leads us to conclude that local ozone depletion and small ozone ‘holes’ may occur in the vicinity of active volcanoes, and that the amount of bromine emitted from volcanoes might be sufficiently large to play a role not only in the stratosphere, but also in tropospheric chemistry.
