Volcano Breath: Measuring Sulfur Dioxide from Space ...

In the presence of sunlight, sulfur dioxide can also mix with oxygen and water vapor to produce volcanic smog, or vog. The sulfur dioxide measured by AIRS, however, occurred above 16 kilometers. At higher altitudes, sulfur dioxide can affect climate. At high altitudes, oxidation transforms this gas into sulfate aerosol particles.

Sulfur Dioxide from Soufriere Hills Volcano

But volcanic gases like sulfur dioxide can cause global cooling, while volcanic carbon dioxide, a greenhouse gas, has the potential to promote global warming. Sulfate aerosols can cool the climate and deplete Earth's ozone layer.

2018's Biggest Volcanic Eruption of Sulfur Dioxide | NASA

In volcanic regions with no sulfur dioxide or monoxide, they saw something else - potassium chloride, another volcanic gas. This suggests that different volcanoes are tapping into different magma reservoirs, rather than sharing them. This suggests some interesting complexity beneath the surface of Io.
