Abstract :
Superconducting Submillimeter-Wave Limb-Emission Sounder (SMILES) has been operated on orbit since late September 2009. The on-orbit performance of the SMILES submillimeter receiver satisfied the specifications and demonstrated a high capability of superconducting technology for atmospheric science by providing an invaluable low-noise atmospheric limb-emission spectral data in 640-GHz band. The accuracy of the limb spectral data are going to be improved by radiometric calibration based on the instrumental knowledge measured on the ground and measurements on orbit. The observation by SMILES was unfortunately halted because of a failure of the submillimeter-wave local oscillator on 21 April 2010.
