AVO Image 11085: Fourpeaked

IMAGE 11085

Image showing the total amount of sulfur dioxide in the atmosphere over Fourpeaked Mountain volcano on September 17, 2006 as measured by the Ozone Monitoring Instrument (OMI) on NASA's Aura satellite. Sulfur dioxide is displayed in Dobson Units (DU), the number of molecules in a square centimeter of the atmosphere. If you were to compress all of the sulfur dioxide a column of the atmosphere into a flat layer at standard temperature and pressure (0 degrees Celsius and 1 atmosphere), one Dobson Unit would be 0.01 millimeters thick and would contain 0.0285 grams of sulfur dioxide per square meter.
