Short summary
The Infrared Atmospheric Sounding Interferometer (IASI) can be used to study volcanic emission of sulfur dioxide (SO2), returning both SO2 amount and altitude data. The series of analyzed eruptions (2008 to 2012) show that the biggest emitter of volcanic SO2 was Nabro, followed by Kasatochi and Grimsvotn. Our observations also show a tendency for volcanic SO2 to reach the level of the tropopause. This tendency was independent of the maximum amount of SO2 and of the volcanic explosive index.
