The innermost Galilean satellite, Io, is known for its active volcanism as well as its essential role in shaping Jupiter’s magnetosphere. Io hosts a tenuous atmosphere, which is supported by sublimation of volcanic-origin surface SO2 deposits as well as gas species directly released from volcanic eruption. In this work, we will use SMA to monitor Io’s atmosphere conditions.
