However, unlike sulfur dioxide, hydrogen sulfide has been challenging to measure in the atmosphere. Clarisse et al. use infrared satellite observations to characterize hydrogen sulfide from the 7-8 August 2008 eruption of the Kasatochi volcano in the Aleutian Islands. The eruption consisted of five explosive events; the observations indicated that the hydrogen sulfide plume was likely associated with the earlier events. The study shows that volcanoes are significant sources of hydrogen sulfide in the atmosphere and demonstrates for the first time that satellites can observe hydrogen sulfide plumes.
