Sulfur Dioxide (OMPS) for the Hunga Tonga Eruption January 2022

Date of Images: 1/14/2022 - 1/25/2022 Date of Next Image: Unknown Summary: The eruption of Hunga Tonga on January 15th was one of the largest eruptions in the last 30 years pushing ash and aerosols high into the atmosphere. Utilizing the OMPS sensor on Suomi-NPP, NASA scientists can measure the sulfur dioxide (SO2) concentration from the eruption. SO2 is often used as a proxy for the location of volcanic ash. High concentrations of SO2 can also be hazardous to human health and air travel. Suggested Use: Green to red colors indicate higher sulfur dioxide (SO2) concentrations Satellite/Sensor: Suomi-NPP Ozone Mapping Profiler Suite (OMPS) Resolution: 375 kilometers Credits: NASA's Direct Readout Laboratory (DRL) Esri REST Endpoint: See URL Section on right side of page WMS Endpoint: https://maps.disasters.nasa.gov/ags04/services/tonga_volcano_tsunami_202201/omps_so2/ImageServer/WMSServer Data Download: https://maps.disasters.nasa.gov/download/gis_products/event_specific/2022/tonga_volcano_tsunami_202201/omps/
