Global Ozone Monitoring Instrument - Sulfur Dioxide (SO2) & Ash emissions - NOAA

The OMI_SO2 product utilizes the SO2 absorption channels of the Ozone Monitoring Instrument flown aboard NASA's Aura spacecraft to identify and monitor passive SO2 outgassing and SO2/ash emissions from volcanic eruptions. A global composite as well as a set of fixed volcanic regions containing near real time SO2 signatures are updated on a daily basis. Data from NOAA
