| Abstract | Volcanic eruptions can emit large amounts of rock fragments and fine particles (ash) into the atmosphere, as well as several gases, including sulphur dioxide (SO2). These ejecta and emissions are a major natural hazard, not only to the local population, but also to the infrastructure in the vicinity of volcanoes and to aviation. Here, we describe a methodology to retrieve quantitative information about vol- canic SO2 plumes from satellite-borne measurements in the UV/Visible spectral range. The combination of a satellite- based SO2 detection scheme and a state-of-the-art 3D trajec- tory model enables us to confirm the volcanic origin of trace gas signals and to estimate the plume height and the effective emission height. This is demonstrated by case-studies for four selected volcanic eruptions in South and Central Amer- ica, using the GOME, SCIAMACHY and GOME-2 instru- ments. |
