The vertical distribution of volcanic SO 2 plumes measured by IASI
Sulfur dioxide (SO 2 ) is an important atmospheric constituent that plays a crucial role in many atmospheric processes. Volcanic eruptions are a significant source of atmospheric SO 2 and its effects and lifetime depend on the SO 2 injection altitude. The Infrared Atmospheric Sounding Interferometer...

Sulfur dioxide (SO 2 ) is an important atmospheric constituent that plays a crucial role in many atmospheric processes. Volcanic eruptions are a significant source of atmospheric SO 2 and its effects and lifetime depend on the SO 2 injection altitude.
