Let’s talk about Sulphur dioxide (SO2). When volcanoes erupt, SO2 is one of the main gases emitted. Along with the ash, it can be picked up by the planetary winds – in our case the jetstream and be dispersed across the globe. In the two satellite images from the EU’s Copernicus Sentinel5p Satellite, we see SO2 from the #LaSoufriere April 9th eruption moving across the Atlantic. Photo 2 shows the SO2 now reaching across Africa, the Arabian Peninsula and now Asia. Read on as to what the World Meteorological Organization has to say about the SO2 dispersal.
The Volcanic Ash Advisory Centre (VAAC) Washington, with responsibility for the Caribbean Sea area, is continuously monitoring (remotely) the presence of volcanic ash in the atmosphere and is regularly issuing volcanic ash advisories for use by aviation users, including airline operators, air navigation service providers and others, in accordance with international requirements. @nemosvg20 @dem.barbados @cdemacoordinatingunit #lasoufriereeruption2021 #lasoufriere #svg #uwi #uwiseismic
