| Research Abstract |
We executed thespectroscopic/theoretical studies of Marsian and Venusian atmospheres with the instrument developments. (a) Atmospheric dynamics and variations of minor components: [A-1.grounbased observation] Velocity/temperature/H2O2/HDO/ etc. were studied by IR and submm observations. [A-2. Orbiter observations] Temperature/clouds/minor components were studied by Venus Express and Mars Express data sets. [A-3: Numerical models] GCMs were developed and utilized with the observational studies. (B)Spectrometer developments: [B-1. For Ground-based] We succeeded to the development of MIR Heterodyne spectrometer. [B-2. For Orbiter] Base investigation was executed. It was utilized for the studies of Martian / Jovian submm instruments.
