Abstract
The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is a useful tool for detecting low quantities of sulfur dioxide at passively degassing volcanoes such as Lascar volcano, Chile. Two mini-UV spectrometers (MUSes) were used to make transects of Lascar volcano's sulfur dioxide plume on December 7, 2004, during a coordinated overpass of ASTER. SO 2 burdens were retrieved using the thermal infrared channels of the acquired ASTER image. This allowed for a direct comparison between the two methods in order to validate the ASTER SO 2 retrieval. The results were extremely encouraging with ASTER deriving SO 2 fluxes within the range of fluxes obtained by the MUSe.
