Satelliteborne Measurement Technologies: Development of Superconducting Submil-limeter-Wave Limb-Emission Sounder (JEM/SMILES) aboard the International Space Station

摘要

In recent years, stratospheric ozone depletion is one of the most significant global environmental issues. It is well known that stratospheric trace gases, which include chlorine oxides and bromine oxides, play a crucial role in the process of stratospheric ozone destruction. Although the abundances of these trace gases are as low as in the order of parts par billion or less, they are quite efficient to destroy stratospheric ozone by catalytic reactions. In order to establish the techniques to monitor stratospheric Ozone and Ozone depleting molecules, CRL and NASDA are collaborating to develop Superconducting Sub-millimeter-Limb Emission Sounder (JEM/SMILES) to be aboard the Japanese Experiment Module (JEM) of the International Space Station. In this paper, the outline of the JEM/SMILS project and the payload instrument is introduced.
