Short summary
Understanding the lateral extent, altitude, and amount of sulfur dioxide (SO2) is important for studying volcanic clouds in support of aviation safety and for analyzing the effects of volcanoes on global climate. In this study, we detail an enhanced satellite measurement that provides probability distributions for the altitude and concentration of SO2 instead of single estimates using the Cross-track Infrared Sounder (CrIS) on the Joint Polar Satellite System (JPSS) series of satellites.
