New research published in the journal Science details balloon measurements taken all the way over near Réunion Island in the Indian Ocean to understand how volcanic eruptions influence climate and ozone chemistry. The authors say the increased humidity in the stratosphere led to a series of interactions between other components shot out from the volcano that ultimately broke down ozone over the tropical south-western Pacific and Indian Ocean regions.
