Short summary
We present a 19-year (2007–2026) global record of atmospheric sulphur dioxide (SO2) abundances and plume altitudes measured twice a day from space by the Infrared Atmospheric Sounding Interferometers (IASI). The first part of the paper covers the retrieval methodology and detailed comparisons with other satellite measurements. The second part presents an overview of the dataset, offering in particular an analysis of the temporal evolution and vertical distribution of volcanic SO2.
