This image maps sulphur dioxide emissions from the erupting Mount Merapi volcano in Indonesia: “This image shows concentrations of sulfur dioxide on November 4–8, 2010, as observed by the Ozone Monitoring Instrument (OMI) on NASA’s Aura spacecraft. Sulfur dioxide is measured here in Dobson Units: The greatest concentrations appear in dark red-brown; the lowest in light peach.”
