Monitoring volcanic SO2 plumes using the GOME-2 satellite instrument
Volcanic sulfur dioxide is an important indicator for volcanic activity. With GOME-2 it is possible to monitor volcanic emissions on a global scale and daily basis. The SO2 is retrieved using Differential Optical Absorption Spectroscopy (DOAS). To attribute the detected SO2 to a particular volcano and to estimate the height of the eruption plume trajectory matching is applied. The development of the eruption plume is predicted using a dispersion model.
