| Research Abstract |
This study aimed an innovative progress in the remote sensing of volcanic gases by introducing some spectroscopic techniques which have been widely used in the research field of atmospheric science. Followings are the major achievements of this study. (1) Sophistication of the Raman LIDAR system for the water-vapor measurement. This study appended a liquid water channel to the previous instrument, which made separate detection of water vapor and mist in a volcanic plume possible. (2) Development of the high spectrum-resolution LIDAR for the measurement of a temperature profile in a volcanic plume. (3) Fabrication of a low-cost version of the SO2 camera which visualizes the concentration of sulfur dioxide in a volcanic plume.
