Service Description: Dates of Images:
4/8/2021 - ongoing
Date of Next Image:
Daily as possible
Summary:
The eruption of the La Soufriere volcano ejected ash and aerosols 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. This layer measures the concentration in the Planetary Boundary Layer, which is the lowest section of the troposphere.
Suggested Use:
Yellow to brown indicates higher sulfur dioxide (SO2) concentrations
Satellite/Sensor:
Suomi-NPP Ozone Mapping Profiler Suite (OMPS)
Resolution:
50 kilometers
Credits:
NASA's Disasters Program, LANCE.
Data and/or imagery from NASA's Land, Atmosphere Near real-time Capability for EOS (LANCE) system (https://earthdata.nasa.gov/lance), part of NASA's Earth Observing System Data and Information System (EOSDIS).
