An analysis of data from Envisat’s Scanning Imaging Absorption Spectrometer for Atmospheric Chartography (SCIAMACHY) acquired 10 November 2002 shows the sulphur dioxide from Africa’s Nyamuragira volcano has been at levels comparable or higher than those observed at Mt. Etna. Located in the eastern Congo, Nyamuragira first erupted on 26 July 2002.
The colour scale indicates the sulphur dioxide levels in Dobson Units (DUs) used to measure concentrations of gases in the atmosphere.
