Paper Abstract

The author proposes a method to estimate two dimensional spatial distribution of volcanic SO2 using a multispectral scanner in thermal infrared region. Volcanic SO2 flux can be estimated from the spatial distribution of SO2 and the plume flow velocity. As ASETR has both Thermal Infrared Radiometer (TIR) and nadir-backward stereoscopic viewing function, we can estimate volcanic SO2 flux by ASTER data alone. These methods are applied to the Oyama volcano in Miyakejima, Japan. SO2 flux derived from ASTER is 3 - X 1044, which is slightly larger than one derived from COSPEC.
