JEM/SMILES からの観測で得られた大気科学的成果

抄録

Early comparison of ozone (O3), HCl, and HNO3 Level-2 products of the Superconducting Submillimeter-Wave LimbEmission Sounder (SMILES) onboard International Space Station has been conducted. Good agreements are observed among SMILES, Scisat-1/ACE-FTS, EOS-Aura/MLS, and ENVISAT/MIPAS, for O3 and HCl below 45 km. SMILES HNO3 profiles are statistically around 20% higher than ACE-FTS and MIPAS. At higher altitude region, 45-60 km, SMILES O3 and HCl are considerably different from ACE-FTS and/or MLS. It is concluded, although future data updates will be necessary, SMILES O3 and HCl below 45 km are both useful for scientific application with special cautions to the SMILES data quality.
