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.</span></p><p><span style='font-weight:bold;'>Suggested Use:</span></p><p><span>Green to red colors indicate higher sulfur dioxide (SO2) concentrations </span></p><p><span style='font-weight:bold;'>Satellite/Sensor:</span></p><p><span>Suomi-NPP Ozone Mapping Profiler Suite (OMPS)</span></p><p><span style='font-weight:bold;'>Resolution:</span></p><p><span>375 kilometers</span></p><p><span style='font-weight:bold;'>Credits:</span></p><p><span>NASA's Direct Readout Laboratory (DRL)</span></p><p><span style='font-weight:bold;'>Esri REST Endpoint:</span></p><p><span>See URL Section on right side of page</span></p><p><span style='font-weight:bold;'>WMS Endpoint:</span></p><p><a href='https://maps.disasters.nasa.gov/ags04/services/tonga_volcano_tsunami_202201/omps_so2/ImageServer/WMSServer' target='_blank'>https://maps.disasters.nasa.gov/ags04/services/tonga_volcano_tsunami_202201/omps_so2/ImageServer/WMSServer</a></p><p><span style='font-weight: bold;'>Data Download:</span><br /></p><p><a href='https://maps.disasters.nasa.gov/download/gis_products/event_specific/2022/tonga_volcano_tsunami_202201/omps/'><span>https://maps.disasters.nasa.gov/download/gis_products/event_specific/2022/tonga_volcano_tsunami_202201/omps/<br /></span></a></p><p><span></span></p></div>" ;
