Monitoring emissions can offer some insight into volcanic behaviour and is essential for assessing the hazard they present as well as their potential impacts on the environment and climate. Using satellite data, we are able to get a global picture of these emissions. The Earth Observation Data Group in Oxford uses a number of different satellite instruments to study volcanic plumes. One of these is the Infrared Atmospheric Sounding Interferometer (IASI) which has sensitivity to both SO2 and volcanic ash. This allows us to identify pixels which contain SO2 and ash, and then quantify plume properties. With the first instrument launched in 2006 and data becoming available in mid-2007, we now have a rich dataset on global SO2 emissions. This talk will provide an overview of this dataset and will discuss some results from recent eruptions of Raikoke (June 2019) and La Soufrière (April 2021). 1-1-1-1-1-1-1-1-1-1-1-1-1-1 ------------------------------
