Measurements of Sulfur dioxide from the Mount Pinatubo Eruption

Image of SO2 Injected into the Earth Stratosphere by Pinatubo Volcano

In addition to providing valuable information on stratospheric chemistry, the Aura MLS instrument will be able to make measurements on other catastrophic events that have effects on the global climate. The picture above shows measurements of SO2 made after the eruption of Mount Pinatubo in 1991 - these measurements were made by the MLS instrument that was flown on the UARS satellite.
