OMI S02 map
Total column amount of volcanic sulfur dioxide (SO2) from Kilauea volcanic eruption on May 19 2018 in free troposphere measured by Ozone Monitoring Instrument (OMI) on board NASA Aura satellite overlayed on SNPP/VIIRS True Color map. SO2 is criteria pollutant gas, which is harmful to people, plants and animals, causes acid rain and volcanic haze (vog). High resolution VIIRS true color map shows dense volcanic aerosol plume emitted from Kilauea main crater and advected in SW...

Ozone Monitoring Instrument (OMI) on EOS Aura satellite measures ~0.12 Tg  SO2 emission from Aoba (Vanuatu) volcanic eruption
This volcanic SO2 plume data from the Aoba volcano (Vanuatu) explosive eruption on April 5 2018 was retrieved using the Ozone monitoring Instrument (OMI) operational Principal Component Analysis (PCA) algorithm (OMSO2) on April 6. Volcanic SO2 measured by satellite UV sensors allows tracking fast movements of volcanic ash clouds , which present hazard to aviation. In large explosive eruptions volcanic SO2 can be injected directly into lower...
