JEM/SMILES is a heterodyne sub-millimeter receiver which will be installed on the ELM-ES platform of the Japanese Experimental Module (JEM) on the International Space Station in 2003.
The main aims of this project are the development and use of superconducting mixers (superconductor-insulator-superconductor, SIS technology) in a heterodyne sub-millimeter receiver for remote sensing of the atmosphere from space.
The three frequency bands of JEM/SMILES have a bandwidth of 1.2 GHz each and start at 624.3, 625.1, and 649.1 GHz. Besides ozone, several important species for the ozone destruction have signatures in this sub-mm range for example ClO, ClO2, BrO, and HO2 which are involved in the odd chlorine and Cl-Br catalytic cycles, and reservoir gases like HCl, HOCl, HNO3, and H2O2.
