| Zusammenfassung |
| A new generation of super-sensitive submillimeter-wave receivers, employing SIS
(Superconductor-Insulator- Superconductor) technology, will provide new opportunities for
precise remote sensing observation of minor constituents in the atmosphere. SMILES had
been launched at 11/09/2009, and installed on the Japanese Experiment Module (JEM) in the
International Space Station (ISS). SMILES is a collaboration project between NICT and
JAXA.
Mission objectives of SMILES are:
i) Space demonstration of super-sensitive SIS mixer and 4-K mechanical cooler
technology
ii) Super-sensitive global observation of atmospheric minor constituents
JEM/SMILES observes the atmospheric species such as O3, H35Cl, H37Cl, ClO, HO2,
BrO, HOCl, HOBr, HNO3, CH3CN, Ozone isotope species, H2O, and Ice Cloud with the
precisions in a few to several tens percents. Theoretical observation capability was studied
with error analysis. The altitude region of observation is from the upper troposphere to the
mesopouse. SMILES early results will be shown with global distributions (L3 data). The
early comparison/validation of ozone performed with several satellite data, such as MLS,
ACE, OSIRIS and Odin.SMR. The statistical analysis showed the differences were less of 5
percent between SMILES and other satellites data validated. This value was consistent with
theoretical capability. This super technology may allow us to open new issues in atmospheric
science. |
